Frequently , an object detector requires manual labeling , while background subtraction needs a training sequence . To automate the analysis , object detection without a separate training phase becomes a critical task . This paper presents a survey of various techniques related to moving object detection and discussed the optimization process that can lead to improved object detection and the speed of formulating the low rank model for detected object . In this paper , we address the object detection problem by a proposed gradient feature , the Edge Histogram of Oriented Gradient ( Edge-HOG ) . Edge-HOG consists of several blocks arranged along a line or an arc , which is designed to describe the edge pattern . The second stage concerns the application of the local over-complete and sparse structure . For an object detection problem , we propose a sparsity testing technique , where a local over-complete and sparse structure is built to give sparse representations to the text patterns and non-sparse representations to other patterns . Object detection is achieved by identifying patterns that can be sparsely represented by the learned structure . PSNR values obtained from variations in image quality improvements will be seen in its characteristics in object detection methods using the Viola Jones method . The higher PSNR value will definitely produce better accuracy , but improving the image to the best quality will drain resources and a high computational burden so it needs to find a minimum PSNR value that can still be considered good in the object detection process . The minimum PSNR value for the image is said to be feasible to be processed 19.05 dB. The minimum PSNR value before the object can no longer be detected is 12.43 dB. Meanwhile , the classification method uses Support Vector Machine which will be compared to find the best accuracy and time computation . This system is given image input with five types of cedar classification such as Class A , Class B , Class C , Class D , and Class E took using Logitech C930e HD which is integrated with Arduino Uno for object detection process and conveyor . The Experiment achieve 90 % of accuracy with time computation 1,40 s Only Look Once ( YOLOv1 ) and the related improvements of YOLOv2 . We further explore the capability of YOLOv2 by implementing its pre-trained model to do the object detecting tasks in some specific traffic scenes . The four artificially designed traffic scenes include single-car , single-person , frontperson-rearcar and frontcar-rearperson . TSD research is of great significance for improving road traffic safety . In recent years , CNN ( Convolutional Neural Networks ) have achieved great success in object detecting tasks . It shows better accuracy or faster execution speed than traditional method . ClickBAIT reduces the human effort required to perform training in real-time by reducing annotations to single clicks , and employing object tracking to produce additional training events . We implement ClickBAIT for both an image classifier and object detector , and show that it improves the training benefit of clicks from 3 to 7 times on representative video sequences . Object detector with region proposal networks such as Fast/Faster R-CNN [ 1 , 2 ] have shown the state-of-the art performance on several benchmarks . However , they have limited success for detecting small objects . This paper implements a new text region recognition algorithm that can accurately localize image text regions in natural image with complex background . The method is mainly based on the anchor mechanism of the faster R-CNN , taking into account the special features of the text area relative to other object detect tasks , so as to convert the text area detection task in the image into a general object detection task for the small area text . In this way , we can detect the text proposal directly in the convolutional feature map of the neural network , and it can simultaneously predict the text/non- text score of the proposal and the coordinates of each proposal in the image . Analyze the advantages and disadvantages and applying condition of the existing object detecting algorithm , aims to body 's variation and real-time and dynamic , combing with Histogram of Gradient statistic method , classify organ of level-connect mechanism and leaning algorithm based on Adaboost of face-detecting Boosted Cascad algorithm , to realize the object detect in car aided driving system . References the sift algorithm rationale and algorithm tracing steability to match and trace the object by characteristic in local area , eliminate the unuse information , simple the search area and speed the tracing . The method comprises of three parts , which are preprocessing part to reduce image noises , motion detection part by using TV-L1 optical flow algorithm , and performance measure part . The last part will analyze the results of the object detection part in term of the bounding boxes , which are compared with the given ground truth . The proposed method is tested on Fall Down Detection ( FDD ) dataset and compared with Gunnar-Farneback optical flow by measuring intersection over union ( IoU ) of the output with respect to the ground truth bounding box . Providing the image capturing apparatus , image capture method , and image capture program . The image capturing apparatus comprising : image capturing means that captures images of a subject ; detector gripping member from a portion of the captured image of the object image detection , said portion having a certain wherein ; evaluator , which determines an evaluation value of a specific characteristic portion detected by the detector of the digital representation ; a buffer member , which temporarily stores a predetermined amount of time with a delay corresponding to the image ; and a recording operation controller , which determines when the evaluation value satisfies a predetermined condition , control the image capture device to record the image data including the predetermined delayed image buffer components . It has important research significance and application value in video monitoring , autonomous driving and human-computer interaction . In recent years , deep learning has made a breakthrough in the research of image classification and led to the rapid development of object vision detection . This paper briefly introduces the object detection algorithm based on deep learning . section : Introduction One - stage approach is the most efficient and elegant framework for object detection . But for a long time , the performance of one - stage detectors has a large gap from that of two - stage detectors . 3 . Object detection is slow . At test - time , features are extracted from each object proposal in each test image . Figure [ reference ] shows discovered objects in a Seaquest frame . This image illustrates the difficulties in detecting objects : although DISCO correctly classifies the different fish as part of the same class , it also detects a life icon and the oxygen bar as part of that class . subsection : Locality Sensitive Hashing ( LSH ) [ reference ] . For fully supervised object detection ( i.e . , training object detectors using boundingbox - level annotations ) , proposal clusters can be generated by treating the groundtruth boundingboxes as cluster centers . Then object detectors are trained according to the proposal clusters ( e.g . , assigning all proposals the label of the corresponding object class for each cluster ) . It is difficult to fairly compare different detectors as they differ in backbone architectures ( like ResNet , ResNext , Xception ) , pre - training data ( e.g. ImageNet - 5k , JFT , OpenImages ) , different structures in the underlying network ( e.g multi - scale features , deformable convolutions , heavier heads , anchor sizes , path aggregation ) , test time augmentations like flipping , mask tightening , iterative bounding box regression etc . Therefore , we compare our results with SNIP , which is a recent method for training object detectors on an image pyramid . The results are presented in Table [ reference ] . Instance Segmentation is the combination of object detection and semantic segmentation . It requires not only the correct detection of objects with various sizes in an image but also the precise segmentation of each object . As mentioned in Sec . Faster R - CNN and RPN are also used by several other leading entries in these competitions . These results suggest that our method is not only a cost - efficient solution for practical usage , but also an effective way of improving object detection accuracy . section : Related Work Saccades in human vision refers to a sequence of rapid eye movements to fixate different image regions . In the context of object detection algorithms , we use the term broadly to mean selectively cropping and processing image regions ( sequentially or in parallel , pixels or features ) during inference . There has been a long history of using saccades in object detection to speed up inference . Models pre - trained on large - scale datasets have proven to generalize better than randomly initialized ones . Another popular transfer method is taking pre - trained networks as backbone and adding high - level functions , e.g. for object detection and recognition and image segmentation . Our meta - transfer learning leverages the idea of transferring pre - trained weights and aims to As shown in Figure [ reference ] , the visual faces vary a lot as the result of the affecting factors including occlusion on the facial part , different scales , illumination conditions , various poses of person , rich expressions , etc . Recently , remarkable advances of objection detection have been driven by the success of region - based methods . Among recent novel algorithms , Fast / Faster R - CNN are representative R - CNN based methods that perform region - wise detections on the regions of interest ( RoIs ) . We introduce Spatial-Temporal Memory Networks for video object detection . At its core , a novel Spatial-Temporal Memory module ( STMM ) serves as the recurrent computation unit to model long-term temporal appearance and motion dynamics . Video salient object detection aims at discovering the most visually distinctive objects in a video . How to effectively take object motion into consideration during video salient object detection is a critical issue . Existing state-of-the-art methods either do not explicitly model and harvest motion cues or ignore spatial contexts within optical flow images . Secondly , as for the spatiotemporal fusing features , the existing methods simply exploit element-wise addition or concatenation , which not fully explores the contextual information and complementary correlation , thus they can not produce more robust spatiotemporal features . To address these issues , we propose a two-stream based spatiotemporal attention neural network ( STAN ) for video salient object detection . We amply extract the motion information in terms of long short term memory ( LSTM ) network and 3D convolutional operation from optical flow-based prior and video sequences . Video based object detection is basic technology of implementing smart CCTV system . Various features and algorithms are developed to detect object , however computations of them increase with the performance . Based on different video object description , different coding schemes are followed to give out the optimum coding performance . For further exploring the functionality of content based coding , the existed methods for video object analysis are reviewed , compared . A concept of the layered video object analysis is suggested and its relation to the layered coding is addressed in this paper .

A concept of the layered video object analysis is suggested and its relation to the layered coding is addressed in this paper . In this paper , a fully automatic method for fast tracking of video objects in a video sequence using affine invariant normalization is proposed . Initially , the detection of a video object is achieved using a GVF snake . Next , a vector of the affine parameters of each contour of the extracted video object in two successive frames is computed using affine-invariant normalization . The system comprises an intelligent video and electronic patrol linkage subsystem , an anti-theft alarm subsystem , a parking garage management subsystem , an access control subsystem , a fire alarm subsystem , a voice and broadcast subsystem and the like . Subsystem integration adopts a Web services technology to uniformly encapsulate definition information , behavior and work flows as well as construct a service architecture-oriented security precaution integrated system ; data transmission is based on a VOX multi-service optical transmission platform with a ring network self-healing function , the VOX bandwidth is dynamically allocated according to requirements and high-grade security services are allocated to redundant bandwidth in proportion of 1:1 to ensure high reliability and high availability of the services ; patrol is in linkage with a video analysis tripwire alarm module , and an image post-processing mixed dynamic and static threshold is adopted , thus effectively solving the problem of video analysis object detection , and reducing the working strength of monitoring staff , the false alarm rate and missed out rate of the system . Robust and Real time moving object tracking is a problematic issue in computer vision research area . We examine the difficulties of video based detection of object and step by step we analyze these issues . We had applied different approaches on video sequence and difficulties , which is faced in that is resolve through Gaussian Mixture model . Thus , this thesis aims to address the development of techniques for better utilization of 3D scene data in semantic object segmentation and tracking . The video object detection problem is addressed by means of a depth and motion based video object segmentation approach . The combination of depth map segmentation and motion detection forms the foreground object masks . Estimates Figure 1 . Our proposed method aims at distilling the best from the two tasks of object tracking and video object segmentation . Like conventional object trackers , it relies on a simple bounding box initialisation ( blue ) and operates online . The system has the capacity for efficient and accurate recognition of fishes from the video dataset , which is recorded in a setting of biological abundance in a coral reef ecosystem . A simple and effective preprocess for fish detection from the video data has been developed , in which multiple bounding – surrounding boxes are introduced to discriminate between swimming fish and other moving objects , such as moving sea anemones and drifting water plants . Additional data , including images of various features from a number of fish species , taken at various angles and illumination conditions , can form the basis for a fish-category database . Finally , the sensitivity of the model for the number of modelled individuals and the sampling interval is analysed .

In addition to recapitulating known organizational patterns of chromosome interactions , we validate our predictions using fluorescence in situ hybridization ( FISH ) . We uncover two types of intermingling clusters - active and inactive clusters based on enrichment for RNA polymerase II and H3K9me3 , respectively . Based on the value of accuracy we can conclude that the system can identify the fish properly . Keywords : Expert System , Forward Chaining , Fish Identification , Cyprinidae , Android . The proposed method presents proof of a concept giving insights in the applicability of deep learning methods for detection of a genetic changes in DLBCL . In future work we will evaluate our algorithm for automatic pre-screen of DLBCL specimens to obviate FISH analysis in a large number of patients . This paper invested an intelligent production-distribution system with fish category detection and traceability management . The proposed system integrated three modules , production-distribution system , fish category detection , and traceability management considering of practical usage in daily life . Fish detection and identification are important steps towards monitoring fish behavior . The importance of such monitoring step comes from the need for better understanding of the fish ecology and issuing conservative actions for keeping the safety of this vital food resource . PURPOSE : To decrease a transmitted information content of a fish detection image . CONSTITUTION : After fish detection image information is given weight with marker pulses Al to A4 corresponding to each sampling while sampled a plurality of times per unit signal content along a time axis T by a CPU 22 , this fish detection image information is made the Morse code with a coding circuit 25 together with marker pulses A1 to A16 , and is transmitted from an antenna 13 to a display element 15 by a transmitting circuit 26 . In the display 15 , each sampled fish detection image information is synthesized on the basis of the marker pulses A1 to A16 by a CPU 17 . In the simpler detection problem , where the objective is only to detect the presence of fish and not make a complete identification , success rates of over 98 % were obtained using a parallel combination as described above . For the fish detection problem , with incomplete training data , correct responses are still obtained in over 95 % of the test cases . > High Resolution Sonars have been widely used for imaging applications in a variety of areas like sea-bottom profiling , fish-finding , under-sea pipeline laying etc . The main advantage of using acoustic sensors over optical sensors for imaging applications is the capability for attaining relatively longer ranges , more so in turbid waters . Fish species detection , classification and study have been an integral part of marine science research . Processing of fish images require methods having various visual techniques , one of the implementation is pattern recognition . This setting gives rise to the need for correct alignment between visual and semantic concepts , so that the unseen objects can be identified using only their semantic attributes . In this paper , we propose a novel loss function called ' Polarity loss ' , that promotes correct visual-semantic alignment for an improved zero-shot object detection . On one hand , it refines the noisy semantic embeddings via metric learning on a ' Semantic vocabulary ' of related concepts to establish a better synergy between visual and semantic domains . Existing methods mainly focus on object detection with sufficient labelled training data or zero-shot object detection with only concept names . In this paper , we address the challenging problem of zero-shot object detection with natural language description , which aims to simultaneously detect and recognize novel concept instances with textual descriptions . We propose a novel deep learning framework to jointly learn visual units , visual-unit attention and word-level attention , which are combined to achieve word-proposal affinity by an element-wise multiplication . Besides , we propose a rebalanced loss function that emphasizes difficult few-shot cases but avoids overfitting on the novel classes to allow detection of totally unseen classes . Without bells and whistles , our framework can also be used solely for Zero-shot detection and Few-shot detection tasks . We report extensive experiments on Pascal VOC and MS-COCO datasets where our approach is shown to provide significant improvements . We present a novel problem setting in zero-shot learning , zero-shot object recognition and detection in the context . Contrary to the traditional zero-shot learning methods , which simply infers unseen categories by transferring knowledge from the objects belonging to semantically similar seen categories , we aim to understand the identity of the novel objects in an image surrounded by the known objects using the inter-object relation prior . Specifically , we leverage the visual context and the geometric relationships between all pairs of objects in a single image , and capture the information useful to infer unseen categories . We integrate our context-aware zero-shot learning framework into the traditional zero-shot learning techniques seamlessly using a Conditional Random Field ( CRF ) . The proposed algorithm is evaluated on both zero-shot region classification and zero-shot detection tasks . The results on Visual Genome ( VG ) dataset show that our model significantly boosts performance with the additional visual context compared to traditional methods . We discover composite concepts by jointly optimizing the accuracy of concept classifiers and their effectiveness for detecting events . We demonstrate that by combining concepts into composite concepts , we can train more accurate classifiers for the concept vocabulary , which leads to improved zero-shot event detection . Moreover , we demonstrate that by using different logic operators , namely " AND " , " OR " , we discover different types of composite concepts , which are complementary for zero-shot event detection . We perform a search for 20 events in 41 K web videos from two test sets of the challenging TRECVID Multimedia Event Detection 2013 corpus . The experiments demonstrate the superior performance of the discovered composite concepts , compared to present-day alternatives , for zero-shot event detection . Object detection is considered as one of the most challenging problems in computer vision , since it requires correct prediction of both classes and locations of objects in images . In this study , we define a more difficult scenario , namely zero-shot object detection ( ZSD ) where no visual training data is available for some of the target object classes . We present a novel approach to tackle this ZSD problem , where a convex combination of embeddings are used in conjunction with a detection framework . We introduce and tackle the problem of zero-shot object detection ( ZSD ) , which aims to detect object classes which are not observed during training . We work with a challenging set of object classes , not restricting ourselves to similar and/or fine-grained categories cf . Instead of assuming a closed-world environment comprising a fixed number of objects , modern pattern recognition systems need to recognize outliers , identify anomalies , or discover entirely new objects , which is known as zero-shot object recognition . However , many existing zero-shot learning methods are not efficient enough to incrementally update themselves with new samples mixed with known or novel class labels . Zero-Shot Object Recognition via Hierarchical Transfer of Semantic Attributes . Attribute based knowledge transfer has proven very successful in visual object analysis and learning previously unseen classes . Subsequently , inconsistent samples are refined based on their neighbors in HNG . Extensive experiments on five benchmark datasets demonstrate the significant superiority of the learned image-specific attributes over the original class-specific attributes in the zero-shot object classification task . The non-parametric conditional and posterior distribution embedding obtained by our method can be applied to a wide range of Bayesian inference problems . In this paper , we apply it to heterogeneous face recognition and zero-shot object recognition problems . Experimental validation shows that our method produces better results than the comparative algorithms . We also propose an approach to recognize novel actions from videos by learning a joint model that links videos and text . Finally , we present a ranking based approach for zero-shot object segmentation . We represent each unknown object class as a semantic ranking of all the known classes and use this semantic relationship to extend the segmentation model of known classes to segment unknown class objects . Furthermore , a top-down fusion structure is constructed for sufficient cross-modal interactions and cross-level transmissions . The experimental results demonstrate the effectiveness of the proposed cross-modal distillation scheme in zero-shot saliency detection and pre-training on a new modality , as well as the advantages in selecting and fusing cross-modal/cross-level complements . In contrast , all our models are trained on 5 - way , 1 query for 1 - shot and 5 queries for 5 - shot per training episode , with much less training queries than . subsection : Zero - shot Recognition Datasets and settings We follow two ZSL settings : the old setting and the new GBU setting provided by for training / test splits .

CONSTITUTION : After fish detection image information is given weight with marker pulses Al to A4 corresponding to each sampling while sampled a plurality of times per unit signal content along a time axis T by a CPU 22 , this fish detection image information is made the Morse code with a coding circuit 25 together with marker pulses A1 to A16 , and is transmitted from an antenna 13 to a display element 15 by a transmitting circuit 26 . In the display 15 , each sampled fish detection image information is synthesized on the basis of the marker pulses A1 to A16 by a CPU 17 .
In the simpler detection problem , where the objective is only to detect the presence of fish and not make a complete identification , success rates of over 98 % were obtained using a parallel combination as described above . For the fish detection problem , with incomplete training data , correct responses are still obtained in over 95 % of the test cases . >
High Resolution Sonars have been widely used for imaging applications in a variety of areas like sea-bottom profiling , fish-finding , under-sea pipeline laying etc . The main advantage of using acoustic sensors over optical sensors for imaging applications is the capability for attaining relatively longer ranges , more so in turbid waters .
Fish species detection , classification and study have been an integral part of marine science research . Processing of fish images require methods having various visual techniques , one of the implementation is pattern recognition .
This setting gives rise to the need for correct alignment between visual and semantic concepts , so that the unseen objects can be identified using only their semantic attributes . In this paper , we propose a novel loss function called ' Polarity loss ' , that promotes correct visual-semantic alignment for an improved zero-shot object detection . On one hand , it refines the noisy semantic embeddings via metric learning on a ' Semantic vocabulary ' of related concepts to establish a better synergy between visual and semantic domains .
Existing methods mainly focus on object detection with sufficient labelled training data or zero-shot object detection with only concept names . In this paper , we address the challenging problem of zero-shot object detection with natural language description , which aims to simultaneously detect and recognize novel concept instances with textual descriptions . We propose a novel deep learning framework to jointly learn visual units , visual-unit attention and word-level attention , which are combined to achieve word-proposal affinity by an element-wise multiplication .
Besides , we propose a rebalanced loss function that emphasizes difficult few-shot cases but avoids overfitting on the novel classes to allow detection of totally unseen classes . Without bells and whistles , our framework can also be used solely for Zero-shot detection and Few-shot detection tasks . We report extensive experiments on Pascal VOC and MS-COCO datasets where our approach is shown to provide significant improvements .
We present a novel problem setting in zero-shot learning , zero-shot object recognition and detection in the context . Contrary to the traditional zero-shot learning methods , which simply infers unseen categories by transferring knowledge from the objects belonging to semantically similar seen categories , we aim to understand the identity of the novel objects in an image surrounded by the known objects using the inter-object relation prior . Specifically , we leverage the visual context and the geometric relationships between all pairs of objects in a single image , and capture the information useful to infer unseen categories . We integrate our context-aware zero-shot learning framework into the traditional zero-shot learning techniques seamlessly using a Conditional Random Field ( CRF ) . The proposed algorithm is evaluated on both zero-shot region classification and zero-shot detection tasks . The results on Visual Genome ( VG ) dataset show that our model significantly boosts performance with the additional visual context compared to traditional methods .
We discover composite concepts by jointly optimizing the accuracy of concept classifiers and their effectiveness for detecting events . We demonstrate that by combining concepts into composite concepts , we can train more accurate classifiers for the concept vocabulary , which leads to improved zero-shot event detection . Moreover , we demonstrate that by using different logic operators , namely " AND " , " OR " , we discover different types of composite concepts , which are complementary for zero-shot event detection . We perform a search for 20 events in 41 K web videos from two test sets of the challenging TRECVID Multimedia Event Detection 2013 corpus . The experiments demonstrate the superior performance of the discovered composite concepts , compared to present-day alternatives , for zero-shot event detection .
Object detection is considered as one of the most challenging problems in computer vision , since it requires correct prediction of both classes and locations of objects in images . In this study , we define a more difficult scenario , namely zero-shot object detection ( ZSD ) where no visual training data is available for some of the target object classes . We present a novel approach to tackle this ZSD problem , where a convex combination of embeddings are used in conjunction with a detection framework .
We introduce and tackle the problem of zero-shot object detection ( ZSD ) , which aims to detect object classes which are not observed during training . We work with a challenging set of object classes , not restricting ourselves to similar and/or fine-grained categories cf .
Instead of assuming a closed-world environment comprising a fixed number of objects , modern pattern recognition systems need to recognize outliers , identify anomalies , or discover entirely new objects , which is known as zero-shot object recognition . However , many existing zero-shot learning methods are not efficient enough to incrementally update themselves with new samples mixed with known or novel class labels .
Zero-Shot Object Recognition via Hierarchical Transfer of Semantic Attributes . Attribute based knowledge transfer has proven very successful in visual object analysis and learning previously unseen classes .
Subsequently , inconsistent samples are refined based on their neighbors in HNG . Extensive experiments on five benchmark datasets demonstrate the significant superiority of the learned image-specific attributes over the original class-specific attributes in the zero-shot object classification task .
The non-parametric conditional and posterior distribution embedding obtained by our method can be applied to a wide range of Bayesian inference problems . In this paper , we apply it to heterogeneous face recognition and zero-shot object recognition problems . Experimental validation shows that our method produces better results than the comparative algorithms .
We also propose an approach to recognize novel actions from videos by learning a joint model that links videos and text . Finally , we present a ranking based approach for zero-shot object segmentation . We represent each unknown object class as a semantic ranking of all the known classes and use this semantic relationship to extend the segmentation model of known classes to segment unknown class objects .
Furthermore , a top-down fusion structure is constructed for sufficient cross-modal interactions and cross-level transmissions . The experimental results demonstrate the effectiveness of the proposed cross-modal distillation scheme in zero-shot saliency detection and pre-training on a new modality , as well as the advantages in selecting and fusing cross-modal/cross-level complements .
In contrast , all our models are trained on 5 - way , 1 query for 1 - shot and 5 queries for 5 - shot per training episode , with much less training queries than . subsection : Zero - shot Recognition Datasets and settings We follow two ZSL settings : the old setting and the new GBU setting provided by for training / test splits .
