I am writing a program to find duplicate videos, I am pulling frames every 500ms and using ORB to compute. I was looking at using FLANN for matching and heard about index. Reading further it says that you sacrifice accuracy, but I wonder how much. Since I am matching videos I only want 95% or higher matches of frames and will determine video matches by how many frames in common at that accuracy.

My question is, can I use index for this or is it too inaccurate. If I can use index, is there some example of how to correlate matches in the index with the separate frames? Can you point me to some examples of doing this?

My question is, can EDIT: I use have been reading and see that orb is a binary descriptor and the flann matcher I was thinking of using is not for binary descriptors. Does the index for this even work with binary descriptors? Do I need an index or is it too inaccurate. If I can use index, is there some example of how matching binary descriptors by hamming distance fast enough not to correlate matches in the index with the separate frames? Can you point me to some examples of doing this?

Or since I want exact duplicates between different resolutions and compressions, should I use another method? Is orb and flann only for finding vaguely similar objects?need one?
