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.

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.

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.

Any suitable methods or suggestions would be greatly helpful. Thanks in advance

  • it is a bit complex for what I am trying to do. And mainly focused on augmented reality, you have any other framework than can pretty much detect objects present in the image – Varij Sep 16 '14 at 12:08

There are few ways to go about this with OpenCV:

Take a look at Feature Detection and Description for other ideas.

    Thanks, that seems very helpful, What I figured out from your answer is that I want Object Detection using SURF. I hope I can find a way to integrate that into iOS application. – Varij Sep 16 '14 at 13:14
  • It's totally possible. – karlphillip Sep 16 '14 at 14:13
  • Thank you for your answer. The SURF method would be the one I'll be using. All i have to do now is integrate into iOS,for which I am following some online tutorials and examples. Thank you!! – Varij Sep 17 '14 at 04:13
  • @Varij, Just FYI: as far as I remember SURF algorithm is not free for commercial usage. – Ivan Mar 22 '17 at 10:06
  • @varij, can you able to integrate it in iOS. me also looking for the same functionality. please provide the sample code. – Ben Rockey Sep 22 '17 at 06:05
