Hi,
I am trying to build a image recognition system where users upload images to a web portal and then they can scan that image in a mobile phone and upon successful recognition, mobile displays some content to the user.
I have tried using FlannIndex with SURF, but since SURF is patented I can not use it in my application. So I started looking for FAST features with FREAK descriptor. I have built the descriptors for all the images using FREAK, but the problem is when I pass all the image descriptors to FlannBasedMatcher and it identifies any matches, how do I know the matched descriptors belong to which image in the database?
Has anyone tried doing this before?
Any help would be much appreciated. Thank you so much!
