Content-based Image Retrieval ( CBIR ) is an important computer vision application that automatically retrieves images of user interest from large database . It faces several challenges such as semantic gap , small sample size and high dimensionality . The purpose of this Paper is to describe our research on Feature extraction and matching techniques in designing a Content Based Image Retrieval ( CBIR ) system . Due to the enormous increase in image database sizes , as well as its vast deployment in various applications , the need for CBIR development arose . Firstly , this paper outlines a description of the primitive feature extraction techniques like : texture , color , and shape . The literature survey part of the thesis consists of a review of content-based information retrieval in general and also looks at multimodal fusion in CBIR systems and how that has been implemented previously in different scenarios . The work performed for this thesis includes the implementation of hierarchical objects and multimodal relevance sharing into the PicSOM CBIR system . Also extensive experiments with different kinds of multimedia and other hierarchical objects ( segmented images , web-link structures and video retrieval ) were performed to evaluate the usefulness of the hierarchical objects paradigm . In this paper , we study how well our PicSOM CBIR system is able to find prototypical image segments based on imagelevel keywords and automatic image segmentation . We also study different methods for focusing a given keyword on a particular image segment . With DIRECT , content based image retrieval ( CBIR ) is a service that will run autonomously ; the constituent collections will not need to be modified to accommodate DIRECT . DIRECT applies a consistent CBIR mechanism to the entire system and gives CBIR functionality to collections without effort by the collection providers . Collections that do not have their own CBIR system or are not able to invest in a CBIR system ( such as small collections or collections that do not contain a large proportion of images ) will gain greater distribution of their holdings via DIRECT 's CBIR functionality . For each proposed CBIR technique 55 queries are fired on general image database , 75 queries are fired on COIL image database and net average precision and recall are computed . The experimental results show that proposed CBIR techniques gives the better performance in terms of higher precision and recall values with lesser computational complexity than the conventional PCA based CBIR using complete image data . Implementation of CBIR on cloud has various benefits because it provides sufficient storage capacity as well as the desired processing power for operation on images . In this paper , the public and hybrid cloud based architecture of CBIR SaaS model is proposed . On the basis of which the services of CBIR will be dynamically available for the desired systems in increasing the applications such as scalability , flexibility and availability . The AHC algorithm performs grouping using linkage average , single , and complete method . Grouping face images can help improve the search speed of the CBIR based face recognition system . The cluster validation test uses the value of Cophenetic Correlation Coefficien ( CCC ) . The experimental results show that use of BTC over morphological shape images for feature extraction improves the performance of image retrieval with reduced computational complexity for query execution . In all BTC with simple morphological edge extraction based CBIR method ( SMBTC ) gives best performance . More specifically , the user-oriented approach contains six specific areas which include image needs , information seeking , image needs and search behavior , image indexing and access , indexing of image collection , and web image search . On the other hand , for CBIR approaches , it contains feature-based image indexing , shape-based indexing , and IR & CBIR . The recent trends of image retrieval based on the results from author bibliographic coupling analysis show that the domain is expanding to emerging areas of medical images , multimedia , ontology- and tag-based indexing which thus reflects a new paradigm of information environment . There are several applications of the CBIR technique such as forensic laboratories , crime detection , image searching etc . For the purpose of feature extraction of well-matched images from the database , a universal CBIR system utilizes texture , color and shape based techniques . In this presented work , we have offered an efficient approach for the content based image retrieval , where images are decomposed using the wavelet transform , it means that the image features are converted in the matrix form and a color feature data set is prepared . In this work , an attempt has been made to analyse retinal images for Content Based Image Retrieval ( CBIR ) application . Canny edge based CBIR systems are developed with and without preprocessing techniques . Blood vessels of normal and abnormal retinal images are segmented using Canny edge method . PCA projection may damage the structure of features , which are originally discriminative for clustering at the split - nodes and regression at the leaf - nodes . Motivated from content - based image retrieval ( CBIR ) [ reference ][ reference ] , where the coarse - level search uses compressed features , while the fine - level search uses augmented features . And this method , based on the color of image , local property , background and sub-image , implements a comprehensive quality assessment processing . The experimental results indicate that this method is high in time efficiency , could be effectively combined with image retrieval system , and significantly improve searching recall rate and accuracy rate . We have developed an image retrieval system which uses Tree Structured Self-Organizing Maps ( TS-SOMs ) as the method for retrieving images similar to a given set of reference images in a database . It also provides a framework for the research on algorithms and methods for content-based retrieval of images . The retrieval precision and recall are increased effectively . For increasing retrieval performance , some significant conclusions are drawn and an experimental image retrieval system is implemented . The invention discloses a control system in projection mapping and a control method thereof . The control system in projection mapping includes a processing unit , a touch panel , an image projection module and an image retrieving module . The processing unit is for executing an application program , the touch panel is coupled to the processing unit and for receiving a control motion and generating a control signal accordingly ; the image projection module is coupled to the processing unit , the processing unit is for executing the control signal and controlling the image projection module to project a projection information through the application program ; and the image retrieving module is coupled to the processing unit and for capturing the projection information as a first image information , wherein the processing unit is for selectively adding an image object to the first image information and regenerating a second image information through the application program , the image projection module reprojects a projection mapping information corresponding to the second image information . In this day and age spatial image classification has become a challenging task . Many systems are developed based on the different approaches of retrieval but the need of image based retrieval system is of dire need . It takes into account an image as the input query and the images are retrieved based on content of the image which is a complicated task . Convolutional neural network is an effective method to extract high-level semantic features for image database retrieval . To overcome the problem of over-fitting when the number of training samples in dataset is limited , this paper proposes an image database retrieval algorithm based on the framework of transfer learning and feature fusion . Based on the fine-tuning of the pre-trained Convolutional Neural Network ( CNN ) , the proposed algorithm first extracts the semantic features of the images . With increase of image resources in the internet , it brings about new challenges to the previous retrieval theory . This essay havediscussed varies kinds of Image Information retrieval technology that now exists , and looks forward to the development and integration ofthe retrieval technology . Especially , it is a very worrisome problem to purchase a new fashion item that suits to their clothing . In this paper , we propose an image-retrieval-based system for supporting a person 's fashion coordination and purchase of new fashion items . This system provides users an efficient way to know and purchase the fashion items which suit to those in their closets . We propose an image retrieval based method for visual localization in indoor scenes , provided that a geotagged image database in indoor environments is given . For image retrieval , we introduce a voting based image similarity which is robust to geometric image transformations and occlusions . High-accuracy indoor positioning is a prerequisite to satisfy the increasing demands of position-based services in complex indoor scenes . Current indoor visual-positioning methods mainly include image retrieval-based methods , visual landmarks-based methods , and learning-based methods . To better overcome the limitations of traditional methods such as them being labor-intensive , of poor accuracy , and time-consuming , this paper proposes a novel indoor-positioning method with automated red , green , blue and depth ( RGB-D ) image database construction . This paper presents a method of building an image data retrieval system that can accept Japanese sentences and handle subjective expressions . A naive user who has little knowledge about objects in the database is likely to use subjective words to explain what he or she wants , for instance , ‘ ‘ show me a cute one , ’ ’ or ‘ ‘ I would like to have a simpler one . The representation of design elements is divided into several sections at different level . The relevancy between design elements and fashion image is determined by semantic network , in which an image object retrieval model is applied . The weights at each level are initialized and updated with relevance feedback technology . The success of image object retrieval systems relies on the visual bag-of-words paradigm , which allows image retrieval systems to adopt a retrieval strategy analogous to text retrieval . In this paper we propose two spatially-aware retrieval strategies for image object retrieval that replaces the vector space model . In the obstacle detection device and the obstacle detecting method for a motor vehicle , an image retrieval section retrieves a situation of a forward detection range in the form of an image from an output section of the detectable object is a position information of a to be detected for the vehicle object , and an image processing section performs image processing for an area of ​​the image retrieval section based on an output of the output section of the recognizable object for detecting the object from , the image processing section has a first technique , primarily for detecting the position of the object , and a second technique , mainly for tracking the object , wherein the second technology detects the object if the object detection is not possible by means of the first technique . This paper studies the search behavior of an image search retrieval system using the model of an architectural and urban planning database . In this mixed-method study , interviews and surveys were conducted to identify unique search behaviors employed by student-workers at Community Design Solutions , a non-profit architectural and urban planning organization at the School of Architecture and Urban Planning ( SARUP ) located at the University of Wisconsin-Milwaukee . Owing to the portable and excellent phone camera , people now prefer to take photos and share them in social networks with their friends . If a user wants to obtain relevant information about an image , content based image retrieval method can be utilized . Taking the limited bandwidth and instability of wireless channel into account , in this paper we propose an effective scalable mobile image retrieval approach by exploiting the advantage of mobile end that people usually take multiple photos of an object in different viewpoints and focuses . This project presents an approach to index and retrieve images using a compact color descriptor in two color spaces namely HSV , and CIE L*u*v*. A compact color descriptor adopted in the proposed content-based image retrieval system is 127-bit binary Haar color histogram , which is used as an index of the images in the database . The color histogram is obtained for an image using a suitable color space . Hence there is a need of such a image search engine using which the related and exact images can be searched . Reverse image search is such a content-based image retrieval query technique that involves providing the CBIR system with a sample image that it will then base its search upon . Reverse image search can be used to search either data related to the query image or the images related to that image or exact images . Hence there is a need of such a image search engine using which the related and exact images can be searched . Reverse image search is such a content-based image retrieval query technique that involves providing the CBIR system with a sample image that it will then base its search upon . Reverse image search can be used to search either data related to the query image or the images related to that image or exact images . In order to solve the problem of image retrieval in multimedia database , design a kind of content based image retrieval system model , and gives the model of the specific implementation method , feedback mechanism . The content-based image retrieval system framework using human-level features of image contents is presented . The system consists of face detection to locate the human faces within images , face recognition of the similarity measure between a query face and indexed faces within storage . There are various kinds ' methods to method that image retrieval based on shape feature . In this paper , an efficient content-based image information retrieval method which utilizes shape information and color information is proposed . CSS(Curvature Scale Space ) space is used to extract shape information . This paper presents a new based on computer based color image retrieval method , this paper expounds the content-based image retrieval concept , necessity and realistic significance . This method is not only high accuracy , speed , can guarantee the accuracy of image content description , to better meet the visual experience . Also social media portals increasingly face the same requirements . This paper presents a new Content Based Image Retrieval database . It is based on new object representation which is based on approximation of objects by a set of shapes . Before measuring the exact similarity between two objects , we calculate a difference in the shape index , perform rotation normalization , then , estimate accurate similarity , if the difference in the shape index is less than 50 % . The results demonstrate that the proposed approach can significantly improve both the accuracy of similarity measurement and the performance of computational speed , when compared with traditional content based image retrieval method approaches that measure the similarity based on contours . In other words , images were first tagged with text and then searched using a text-based approach from traditional database management systems . In this experimental paper , we propose an effective content-based image retrieval ( searching ) method based on simplest feature that is extracted from images such as combination of multi-resolution colour . The purpose of this paper is to explore a new possibility which enables searching of the images an easy and user friendly task which is rather cumbersome in nature . Internet sources of visual information are diffused and dispersed over the whole Web , so the duty of information content evaluation must be relegated now to an image content understanding machine or a computer-based program capable to perform image content evaluation at a distant image location . Development of Content Based Image Retrieval ( CBIR ) technologies is a natural move in the right direction . However ... Secure and efficient retrieval of multimedia information from archives of large biomedical images for teaching , research and development of diagnostic tools have become a necessity in today 's global environment . Most traditional content-based image retrieval ( CBIR ) systems do not address the challenges involved in high fidelity and efficient retrieval of diverse classes of biomedical imagery through secure transmission over the Internet . We present the development and validation of a source encoding scheme in the wavelet domain with an embedded backward coding of wavelet trees ( BCWT ) for encoding of multiple image classes archived at the National Library of Medicine . Performance evaluation of content-based image retrieval ( CBIR ) systems is an important but still unsolved problem . The reason for its importance is that only performance evaluation allows for comparison and integration of different CBIR systems . Addressing this issue , we designed an innovative approach to obtain an accurate label for images by taking into account the social aspects of human-based computation . The proposed approach is highly discriminative in comparison to an ordinary content-based image retrieval ( CBIR ) paradigm . It aims at what millions of individual gamers are enthusiastic to do , to enjoy themselves within a social competitive environment . It focuses on computer gaming and the use of humans in a widely distributed fashion . This approach deviates from the conventional “ content-based image retrieval ( CBIR ) ” paradigm favoured by the research community to tackle the problems related to the semantic annotation and tagging of multimedia contents . The proposed approach uses a multifaceted mathematical model based on game theories to aggregate numbers of different key-paradigms , such as Image Processing , Machine Learning and Game based approaches to generate accurate annotations . As image databases are growing at a rapid rate , demand for efficient and effective tools for retrieval of images increased significantly . Among them , content-based image retrieval systems ( CBIR ) have become very popular for browsing , searching and retrieving images from a large database of digital images . Biometric security methods have been gaining importance increasingly in the recent years due to advances in biometrics technology and its reliability and efficiency in real world applications . The recognition process uses the k-NN method . The Content-Based Image Retrieval ( CBIR ) process uses image features ( visual contents ) to perform image searches from the database . Experimental results and analysis of fruit recognition system obtained an accuracy of 92.5 % for single-object images and 90 % for the multi-object image . The difficulty of finding some specific images from a database creates a need for a system that applies the Content-Based Image Retrieval ( CBIR ) concept . Publicly , a CBIR system is a system that able to search and retrieve the desired images that have similarity in both visual characteristics and relevance terms . Use of Bitmap helps learn the feedback obtained from multiple users regarding the relevance between various images until a saturation point is reached . The results show its superiority in comparison with existing models such as QBIC , MARS and VIPER techniques . We examine ways of choosing the threshold value in either case . In our study we use Oracle database and IBM QBIC . The interface between the Matlab workspace and the database is described . The Oracle Database and the IBM QBIC are used for investigation purposes . The virage system allows queries to be built by combining color , colour layout , texture , and object boundary information . The original Query by Image Content ( QBIC ) system allowed the user to select the relative importance of color , texture , and shape . This paper provides the survey of technical achievements in the research area of image retrieval , especially content based image retrieval(CBIR ) . Examples of the content include color , color layout , texture , shape , size , orientation , and position of image objects and regions . We have developed an AIX prototype , WWW QBIC server with WWW demo , and a product called Ultimedia Manager ( OS/2 and Windows ) . The key applications of this technology are in the areas where image patterns are the basis of the queries , and where keywords are not precise enough for satisfactory retrieval , such as in on-line stock photo , retail , art etc .

To copy otherwise , to republish , to post on servers or to redistribute to lists , requires prior specific permission and/or a fee . " present a short overview of QBIC technology and products , and summarize the above applications . Introduction to Query by Image Content ( QBIC ) desktop publishers , graphic designers , and consumers can now quickly and inexpensively search for and print thousands of high-quality , royalty-free images via the lnternet , using QBIC technology . The agreement will enable Internet users to search for stock images and clip art by selecting attributes including color , texture , and shape using IBM ° s award-winning Query by Image Content ( QBIC ) technology . These images can be quickly transmitted to loeat or distant PIP Printing centers using REPRINT , SEDONA 's document communications software . In this work , feature vectors in a given image are ordered by the principal axis analysis to speed up the similarity search in a high-dimensional image database using k nearest neighbor searches . To demonstrate the effectiveness of the proposed algorithm , we conducted extensive experiments and compared the performance with the IBMs query by image content ( QBIC ) method , Jain and Vailays method , and the LPC-file method . The experimental results demonstrate that the proposed method outperforms the compared methods in retrieval accuracy and execution speed . Query optimization needs to be adapted to this essentially different query model for multimedia data . Some systems have already been implemented , e.g. visual retrieval systems like IBM 's QBIC [ 1 ] or Virage 's VIR [ 2 ] . Database applications and middlewares like GARLIC [ 3 ] or the HERON project [ 4 ] have already started to use the capabilities of visual retrieval . Although information retrieval is already a mature research area for text databases , its use for video and image libraries is relatively new . Some of the earliest and largest research efforts have been IBM Almaden 's QBIC system [ l ] , ISSs SWIM system [ 21 , and MIT 's Photobook and FourEyes systems [ 3 ] , [ 4 ] . Pieces of these first systems have evolved into commercial products and can be explored interactively on the world-wide web [ 5 ] , [ 61 . Query By Image Content ( QBIC ) system permits the user to extract similar images from the large database by specifying the query image . In this paper , a new hybrid QBIC system is proposed , which effectively utilizes the color , texture , and shape features by sequential process of three pipe stages which gives good retrieval performance and also reduces computational complexity . In first pipe stage , color features are extracted with histograms based on HSV color space . It is often the case that a good solution to a problem in one application set-up may not be the one the user is looking for in another situation . For example , using query by image content ( QBIC ) approach to performing image retrieval , the user can use an example image as query . Suppose that a user has picked an image containing a horse in the foreground , blue sky and green grass in the background as the querying image . The system computes a set of features to describe the above properties , uses distance-like measures on the features to provide similarity based retrieval , and has a graphical interface that enable users pose queries visually . In this paper , we present QBIC indexing algorithms that allow these " multi- * " queries to run efficiently . The authors conducted the Web Retrieval Task ( ’ NTCIR-3 WEB ’ ) from 2001 to 2002 at the Third NTCIR Workshop . In the NTCIR-3 WEB , they attempted to assess the retrieval effectiveness of Web search engine systems using a common data set , and to build re-usable test collections that are suitable for evaluating Web information retrieval systems . With these objectives , they evaluated on searches using various types of user input , user models and document models . Contrary to traditional Web information retrieval methods that can only return a ranked list of Web pages and only allow search terms in the query , we have developed a novel learning framework for retrieving precise information blocks from Web pages given a query , which may contain some search terms and prior information such as the layout format of the data . There are two challenging sub-tasks for this problem . The definition of Web information retrieval is given . Working principle and performing methods of Web information retrieval system are demonstrated in detail . In order to solve the existent problems , by integrating neural network algorithm , best first search , information filtering algorithm , relevant feedback algorithm , etc , an Agent based model of personalized intelligent Web information retrieval is presented . More often they would like to get targeted answers to their queries without extraneous information , even if their requirements are not well specified . In this paper we propose an approach for designing a web retrieval system able to find the desired information through several interactions with the users . The proposed approach allows to overcome the problems deriving from ambiguous or too vague queries , using semantic search and topic detection techniques . In this paper we propose an efficient method of extracting the image color content , which can serve as an image digital signature , allowing the efficient indexing and retrieval of large Internet-based multimedia databases . We applied the proposed method using the images from two Internet databases containing a collection of images of fine arts and a database of low resolution images , and show that the new method of image color representation is robust to image distorsions caused by resizing and compression and can be incorporated into existing web-based retrieval systems , that exploit the information on color content of digital images . In contrast , SEAL allows the users to retrieve the necessary data by using metadata associated with contents , such as physical values , of a data file . We confirmed that SEAL can reduce data sizes and total time required for obtaining necessary data to less than 0.5 % and 1 % , respectively , compared to conventional web-based retrieval systems . Accessing information on the Web has become ingrained into our daily lives , and we seek information from many different sources , including conference and journal publications , personal web pages , and others . Increasingly , web-based information retrieval systems such as web-based search engines , library on-line catalog systems , and subscription-based federated search systems are made available to provide an interface to collections of information from these sources . Because the quantity of new information available every day exceeds how much information individuals can handle effectively , we spend significant effort in locating information , often unsuccessfully . At present , information derived from the cross-references among pages is used to improve the results of Web-based information retrieval systems , as constantly occur in bibliometric techniques . The references are local when only the links related to the set of documents returned as answers to a user query are treated , as done by the HITS algorithm . For this goal all articles of 24 journals related to medical informatics and medical imaging were crawled from the web pages of BioMed Central . Text and images of the PDF ( Portable Document Format ) files were indexed separately and a web-based retrieval interface allows for searching via keyword queries or by visual similarity queries . Starting point for a visual similarity query can be an image on the local hard disk that is uploaded or any image found via the textual search . WebPut consults the Web for imputing the missing values in a local database when the traditional inferring-based imputation method has difficulties in getting the right answers . Specifically , WebPut investigates the interaction between the local inferring-based imputation methods and the web-based retrieving methods and shows that retrieving a small number of selected missing values can greatly improve the imputation recall of the inferring-based methods . Besides , WebPut also incorporates a crowd intervention component that can get advice from humans in case that the web-based imputation methods may have difficulties in making the right decisions . Reaxys - The Online Version of Beilstein Crossfire : Reaxys - Help , FAQs , and Online Training Modules . An online chemical encyclopedia , containing all the important information about more than 7 million organic chemical compounds , inorganic compounds , and chemical and life sciences patents from the United States ( since 1976 ) and the World ( since 1978 ) Reaxys is a web-based search and retrieval system for chemical compounds , bibliographic data and chemical reactions . Both human evaluations and automatic metrics are used to evaluate the retrieved descriptions . Results show that the web-retrieval-based approach performed better when describing single-object images with sentences extracted from stock photography websites . On the other hand , images with two image objects were better described with template-generated sentences composed of object labels and prepositions . Existing index structures such as extendable hashing and B+-tree do not support partial string searches perfectly . The inverted file method and the signature file method that are used in the web retrieval engine also have problems that they do not provide partial string searches and suffer from serious retrieval performance degradation respectively . In this paper , we propose an efficient index method that supports partial string searches and achieves good retrieval performance . IntelliSearch stores a crawl of the Web with more than 1,5 million Web pages with images and is accessible on the Internet . It offers an ideal test-bed for experimentation and training and serves as a framework for a realistic evaluation of many Web image retrieval methods . However , local text information , such as caption , filenames and adjacent text , is not always reliable and informative . Therefore , global information should be taken into account when a Web image retrieval system makes relevance judgment . We propose a re-ranking method to improve Web image retrieval by reordering the images retrieved from an image search engine . Web image retrieval has characteristics different from typical content-based image retrieval ; web images have associated textual cues . However , a web image retrieval system often yields undesirable results , because it uses limited text information such as surrounding text , URLs , and image filenames . In this paper , we propose a new approach to retrieval , which uses the image content of retrieved results without relying on assistance from the user . This extended SHORE storage system provides conventional storage manager functions , guarantees the integrity of high-dimensional data and is flexible to the large scale of feature vectors for preventing the usage of large main memory . Finally , we implement the web-based image retrieval system by using the extended SHORE storage system . The key feature of this system is platform-independent access to the high-dimensional data as well as functionality of efficient content-based queries . iFind © ( v1.0 ) is a web-based image retrieval system developed at Microsoft Research China . It provides the functionalities of text based image search , query by image example , and their combination . In this paper we propose an efficient method of extracting the image color content , which serves as a digital signature , allowing to ef- ficiently index and retrieve large multimedia Internet based databases . We applied the proposed method using the images from the WEBMU- SEUM Internet database containing the collection of images of fine arts and show that the new method of image color representation is robust to image resizing and compression and therefore can be incorporated into existing web-based image retrieval systems . Image retrieval methods based on color , texture shape and semantics are discussed , analyzed and compared . The semantic based image retrieval is a better way to solve the semantic - gap problem , so Ontology - based web image retrieval method is stressed in this article . This model considers the ontological requirements in usability , intelligence and effectiveness . Thus automatic image annotationhas drawn the attention of the researchers in recent years .. The increase in social web application and the semantic web drawn attention of researchers in the development of several web-based image retrieval tools . This paper presents an easy , efficient image retrieval approach using a new image feature descriptor called Micro-Structure Descriptor ( MSD ) .

In this paper , we propose an image-retrieval-based system for supporting a person 's fashion coordination and purchase of new fashion items . This system provides users an efficient way to know and purchase the fashion items which suit to those in their closets .
We propose an image retrieval based method for visual localization in indoor scenes , provided that a geotagged image database in indoor environments is given . For image retrieval , we introduce a voting based image similarity which is robust to geometric image transformations and occlusions .
High-accuracy indoor positioning is a prerequisite to satisfy the increasing demands of position-based services in complex indoor scenes . Current indoor visual-positioning methods mainly include image retrieval-based methods , visual landmarks-based methods , and learning-based methods . To better overcome the limitations of traditional methods such as them being labor-intensive , of poor accuracy , and time-consuming , this paper proposes a novel indoor-positioning method with automated red , green , blue and depth ( RGB-D ) image database construction .
This paper presents a method of building an image data retrieval system that can accept Japanese sentences and handle subjective expressions . A naive user who has little knowledge about objects in the database is likely to use subjective words to explain what he or she wants , for instance , ‘ ‘ show me a cute one , ’ ’ or ‘ ‘ I would like to have a simpler one .
The representation of design elements is divided into several sections at different level . The relevancy between design elements and fashion image is determined by semantic network , in which an image object retrieval model is applied . The weights at each level are initialized and updated with relevance feedback technology .
The success of image object retrieval systems relies on the visual bag-of-words paradigm , which allows image retrieval systems to adopt a retrieval strategy analogous to text retrieval . In this paper we propose two spatially-aware retrieval strategies for image object retrieval that replaces the vector space model .
In the obstacle detection device and the obstacle detecting method for a motor vehicle , an image retrieval section retrieves a situation of a forward detection range in the form of an image from an output section of the detectable object is a position information of a to be detected for the vehicle object , and an image processing section performs image processing for an area of ​​the image retrieval section based on an output of the output section of the recognizable object for detecting the object from , the image processing section has a first technique , primarily for detecting the position of the object , and a second technique , mainly for tracking the object , wherein the second technology detects the object if the object detection is not possible by means of the first technique .
This paper studies the search behavior of an image search retrieval system using the model of an architectural and urban planning database . In this mixed-method study , interviews and surveys were conducted to identify unique search behaviors employed by student-workers at Community Design Solutions , a non-profit architectural and urban planning organization at the School of Architecture and Urban Planning ( SARUP ) located at the University of Wisconsin-Milwaukee .
Owing to the portable and excellent phone camera , people now prefer to take photos and share them in social networks with their friends . If a user wants to obtain relevant information about an image , content based image retrieval method can be utilized . Taking the limited bandwidth and instability of wireless channel into account , in this paper we propose an effective scalable mobile image retrieval approach by exploiting the advantage of mobile end that people usually take multiple photos of an object in different viewpoints and focuses .
This project presents an approach to index and retrieve images using a compact color descriptor in two color spaces namely HSV , and CIE L*u*v*. A compact color descriptor adopted in the proposed content-based image retrieval system is 127-bit binary Haar color histogram , which is used as an index of the images in the database . The color histogram is obtained for an image using a suitable color space .
Hence there is a need of such a image search engine using which the related and exact images can be searched . Reverse image search is such a content-based image retrieval query technique that involves providing the CBIR system with a sample image that it will then base its search upon . Reverse image search can be used to search either data related to the query image or the images related to that image or exact images .

In order to solve the problem of image retrieval in multimedia database , design a kind of content based image retrieval system model , and gives the model of the specific implementation method , feedback mechanism .
The content-based image retrieval system framework using human-level features of image contents is presented . The system consists of face detection to locate the human faces within images , face recognition of the similarity measure between a query face and indexed faces within storage .
There are various kinds ' methods to method that image retrieval based on shape feature . In this paper , an efficient content-based image information retrieval method which utilizes shape information and color information is proposed . CSS(Curvature Scale Space ) space is used to extract shape information .
This paper presents a new based on computer based color image retrieval method , this paper expounds the content-based image retrieval concept , necessity and realistic significance . This method is not only high accuracy , speed , can guarantee the accuracy of image content description , to better meet the visual experience .
Also social media portals increasingly face the same requirements . This paper presents a new Content Based Image Retrieval database . It is based on new object representation which is based on approximation of objects by a set of shapes .
Before measuring the exact similarity between two objects , we calculate a difference in the shape index , perform rotation normalization , then , estimate accurate similarity , if the difference in the shape index is less than 50 % . The results demonstrate that the proposed approach can significantly improve both the accuracy of similarity measurement and the performance of computational speed , when compared with traditional content based image retrieval method approaches that measure the similarity based on contours .
In other words , images were first tagged with text and then searched using a text-based approach from traditional database management systems . In this experimental paper , we propose an effective content-based image retrieval ( searching ) method based on simplest feature that is extracted from images such as combination of multi-resolution colour . The purpose of this paper is to explore a new possibility which enables searching of the images an easy and user friendly task which is rather cumbersome in nature .
Internet sources of visual information are diffused and dispersed over the whole Web , so the duty of information content evaluation must be relegated now to an image content understanding machine or a computer-based program capable to perform image content evaluation at a distant image location . Development of Content Based Image Retrieval ( CBIR ) technologies is a natural move in the right direction . However ...
Secure and efficient retrieval of multimedia information from archives of large biomedical images for teaching , research and development of diagnostic tools have become a necessity in today 's global environment . Most traditional content-based image retrieval ( CBIR ) systems do not address the challenges involved in high fidelity and efficient retrieval of diverse classes of biomedical imagery through secure transmission over the Internet . We present the development and validation of a source encoding scheme in the wavelet domain with an embedded backward coding of wavelet trees ( BCWT ) for encoding of multiple image classes archived at the National Library of Medicine .
Performance evaluation of content-based image retrieval ( CBIR ) systems is an important but still unsolved problem . The reason for its importance is that only performance evaluation allows for comparison and integration of different CBIR systems .
Addressing this issue , we designed an innovative approach to obtain an accurate label for images by taking into account the social aspects of human-based computation . The proposed approach is highly discriminative in comparison to an ordinary content-based image retrieval ( CBIR ) paradigm . It aims at what millions of individual gamers are enthusiastic to do , to enjoy themselves within a social competitive environment .
It focuses on computer gaming and the use of humans in a widely distributed fashion . This approach deviates from the conventional “ content-based image retrieval ( CBIR ) ” paradigm favoured by the research community to tackle the problems related to the semantic annotation and tagging of multimedia contents . The proposed approach uses a multifaceted mathematical model based on game theories to aggregate numbers of different key-paradigms , such as Image Processing , Machine Learning and Game based approaches to generate accurate annotations .
As image databases are growing at a rapid rate , demand for efficient and effective tools for retrieval of images increased significantly . Among them , content-based image retrieval systems ( CBIR ) have become very popular for browsing , searching and retrieving images from a large database of digital images . Biometric security methods have been gaining importance increasingly in the recent years due to advances in biometrics technology and its reliability and efficiency in real world applications .
The recognition process uses the k-NN method . The Content-Based Image Retrieval ( CBIR ) process uses image features ( visual contents ) to perform image searches from the database . Experimental results and analysis of fruit recognition system obtained an accuracy of 92.5 % for single-object images and 90 % for the multi-object image .
The difficulty of finding some specific images from a database creates a need for a system that applies the Content-Based Image Retrieval ( CBIR ) concept . Publicly , a CBIR system is a system that able to search and retrieve the desired images that have similarity in both visual characteristics and relevance terms .
Use of Bitmap helps learn the feedback obtained from multiple users regarding the relevance between various images until a saturation point is reached . The results show its superiority in comparison with existing models such as QBIC , MARS and VIPER techniques .
We examine ways of choosing the threshold value in either case . In our study we use Oracle database and IBM QBIC .
The interface between the Matlab workspace and the database is described . The Oracle Database and the IBM QBIC are used for investigation purposes .
The virage system allows queries to be built by combining color , colour layout , texture , and object boundary information . The original Query by Image Content ( QBIC ) system allowed the user to select the relative importance of color , texture , and shape . This paper provides the survey of technical achievements in the research area of image retrieval , especially content based image retrieval(CBIR ) .
Examples of the content include color , color layout , texture , shape , size , orientation , and position of image objects and regions . We have developed an AIX prototype , WWW QBIC server with WWW demo , and a product called Ultimedia Manager ( OS/2 and Windows ) . The key applications of this technology are in the areas where image patterns are the basis of the queries , and where keywords are not precise enough for satisfactory retrieval , such as in on-line stock photo , retail , art etc .

" present a short overview of QBIC technology and products , and summarize the above applications . Introduction to Query by Image Content ( QBIC )
desktop publishers , graphic designers , and consumers can now quickly and inexpensively search for and print thousands of high-quality , royalty-free images via the lnternet , using QBIC technology . The agreement will enable Internet users to search for stock images and clip art by selecting attributes including color , texture , and shape using IBM ° s award-winning Query by Image Content ( QBIC ) technology . These images can be quickly transmitted to loeat or distant PIP Printing centers using REPRINT , SEDONA 's document communications software .
In this work , feature vectors in a given image are ordered by the principal axis analysis to speed up the similarity search in a high-dimensional image database using k nearest neighbor searches . To demonstrate the effectiveness of the proposed algorithm , we conducted extensive experiments and compared the performance with the IBMs query by image content ( QBIC ) method , Jain and Vailays method , and the LPC-file method . The experimental results demonstrate that the proposed method outperforms the compared methods in retrieval accuracy and execution speed .
Query optimization needs to be adapted to this essentially different query model for multimedia data . Some systems have already been implemented , e.g. visual retrieval systems like IBM 's QBIC [ 1 ] or Virage 's VIR [ 2 ] . Database applications and middlewares like GARLIC [ 3 ] or the HERON project [ 4 ] have already started to use the capabilities of visual retrieval .
Although information retrieval is already a mature research area for text databases , its use for video and image libraries is relatively new . Some of the earliest and largest research efforts have been IBM Almaden 's QBIC system [ l ] , ISSs SWIM system [ 21 , and MIT 's Photobook and FourEyes systems [ 3 ] , [ 4 ] . Pieces of these first systems have evolved into commercial products and can be explored interactively on the world-wide web [ 5 ] , [ 61 .
Query By Image Content ( QBIC ) system permits the user to extract similar images from the large database by specifying the query image . In this paper , a new hybrid QBIC system is proposed , which effectively utilizes the color , texture , and shape features by sequential process of three pipe stages which gives good retrieval performance and also reduces computational complexity . In first pipe stage , color features are extracted with histograms based on HSV color space .
It is often the case that a good solution to a problem in one application set-up may not be the one the user is looking for in another situation . For example , using query by image content ( QBIC ) approach to performing image retrieval , the user can use an example image as query . Suppose that a user has picked an image containing a horse in the foreground , blue sky and green grass in the background as the querying image .
The system computes a set of features to describe the above properties , uses distance-like measures on the features to provide similarity based retrieval , and has a graphical interface that enable users pose queries visually . In this paper , we present QBIC indexing algorithms that allow these " multi- * " queries to run efficiently .
The authors conducted the Web Retrieval Task ( ’ NTCIR-3 WEB ’ ) from 2001 to 2002 at the Third NTCIR Workshop . In the NTCIR-3 WEB , they attempted to assess the retrieval effectiveness of Web search engine systems using a common data set , and to build re-usable test collections that are suitable for evaluating Web information retrieval systems . With these objectives , they evaluated on searches using various types of user input , user models and document models .
Contrary to traditional Web information retrieval methods that can only return a ranked list of Web pages and only allow search terms in the query , we have developed a novel learning framework for retrieving precise information blocks from Web pages given a query , which may contain some search terms and prior information such as the layout format of the data . There are two challenging sub-tasks for this problem .
The definition of Web information retrieval is given . Working principle and performing methods of Web information retrieval system are demonstrated in detail . In order to solve the existent problems , by integrating neural network algorithm , best first search , information filtering algorithm , relevant feedback algorithm , etc , an Agent based model of personalized intelligent Web information retrieval is presented .
More often they would like to get targeted answers to their queries without extraneous information , even if their requirements are not well specified . In this paper we propose an approach for designing a web retrieval system able to find the desired information through several interactions with the users . The proposed approach allows to overcome the problems deriving from ambiguous or too vague queries , using semantic search and topic detection techniques .
In this paper we propose an efficient method of extracting the image color content , which can serve as an image digital signature , allowing the efficient indexing and retrieval of large Internet-based multimedia databases . We applied the proposed method using the images from two Internet databases containing a collection of images of fine arts and a database of low resolution images , and show that the new method of image color representation is robust to image distorsions caused by resizing and compression and can be incorporated into existing web-based retrieval systems , that exploit the information on color content of digital images .
In contrast , SEAL allows the users to retrieve the necessary data by using metadata associated with contents , such as physical values , of a data file . We confirmed that SEAL can reduce data sizes and total time required for obtaining necessary data to less than 0.5 % and 1 % , respectively , compared to conventional web-based retrieval systems .
Accessing information on the Web has become ingrained into our daily lives , and we seek information from many different sources , including conference and journal publications , personal web pages , and others . Increasingly , web-based information retrieval systems such as web-based search engines , library on-line catalog systems , and subscription-based federated search systems are made available to provide an interface to collections of information from these sources . Because the quantity of new information available every day exceeds how much information individuals can handle effectively , we spend significant effort in locating information , often unsuccessfully .
At present , information derived from the cross-references among pages is used to improve the results of Web-based information retrieval systems , as constantly occur in bibliometric techniques . The references are local when only the links related to the set of documents returned as answers to a user query are treated , as done by the HITS algorithm .
For this goal all articles of 24 journals related to medical informatics and medical imaging were crawled from the web pages of BioMed Central . Text and images of the PDF ( Portable Document Format ) files were indexed separately and a web-based retrieval interface allows for searching via keyword queries or by visual similarity queries . Starting point for a visual similarity query can be an image on the local hard disk that is uploaded or any image found via the textual search .
WebPut consults the Web for imputing the missing values in a local database when the traditional inferring-based imputation method has difficulties in getting the right answers . Specifically , WebPut investigates the interaction between the local inferring-based imputation methods and the web-based retrieving methods and shows that retrieving a small number of selected missing values can greatly improve the imputation recall of the inferring-based methods . Besides , WebPut also incorporates a crowd intervention component that can get advice from humans in case that the web-based imputation methods may have difficulties in making the right decisions .
Reaxys - The Online Version of Beilstein Crossfire : Reaxys - Help , FAQs , and Online Training Modules . An online chemical encyclopedia , containing all the important information about more than 7 million organic chemical compounds , inorganic compounds , and chemical and life sciences patents from the United States ( since 1976 ) and the World ( since 1978 ) Reaxys is a web-based search and retrieval system for chemical compounds , bibliographic data and chemical reactions .
Both human evaluations and automatic metrics are used to evaluate the retrieved descriptions . Results show that the web-retrieval-based approach performed better when describing single-object images with sentences extracted from stock photography websites . On the other hand , images with two image objects were better described with template-generated sentences composed of object labels and prepositions .
Existing index structures such as extendable hashing and B+-tree do not support partial string searches perfectly . The inverted file method and the signature file method that are used in the web retrieval engine also have problems that they do not provide partial string searches and suffer from serious retrieval performance degradation respectively . In this paper , we propose an efficient index method that supports partial string searches and achieves good retrieval performance .
IntelliSearch stores a crawl of the Web with more than 1,5 million Web pages with images and is accessible on the Internet . It offers an ideal test-bed for experimentation and training and serves as a framework for a realistic evaluation of many Web image retrieval methods .
However , local text information , such as caption , filenames and adjacent text , is not always reliable and informative . Therefore , global information should be taken into account when a Web image retrieval system makes relevance judgment . We propose a re-ranking method to improve Web image retrieval by reordering the images retrieved from an image search engine .
Web image retrieval has characteristics different from typical content-based image retrieval ; web images have associated textual cues . However , a web image retrieval system often yields undesirable results , because it uses limited text information such as surrounding text , URLs , and image filenames . In this paper , we propose a new approach to retrieval , which uses the image content of retrieved results without relying on assistance from the user .
This extended SHORE storage system provides conventional storage manager functions , guarantees the integrity of high-dimensional data and is flexible to the large scale of feature vectors for preventing the usage of large main memory . Finally , we implement the web-based image retrieval system by using the extended SHORE storage system . The key feature of this system is platform-independent access to the high-dimensional data as well as functionality of efficient content-based queries .
