title: Image matching with real objects in iOS
body: <p>I have a database of images of various articles and the related information. Am creating an application in which user can scan/click an image of the real object and the application should match that image with the images in the database and identify which object was scanned/clicked by the user.</p>
  
  <p>For example: user scans a fish(catfish for eg.), the application should check the images in the database and tell if it(catfish) is present or not. </p>
  
  <p>I want this implementation in an iOS application.
  Am trying to use OpenCV for this, but I cant find proper documentation to how to implement object detection and comparison in iOS.</p>
  
  <p>Any suitable methods or suggestions would be greatly helpful.
  Thanks in advance</p>
