Hi I was curious if anyone has tried to store ORB or SIFT descriptors to use for an image similarity search?
At a high level i’m using opencv ORB and SIFT implementations to get feature vectors ie descriptors which results in a Mx32 for ORB and and Mx128 for SIFT matrix where M is based on the number of keypoints found in an image.
I was looking to see if there was a way to store those feature vectors in such a way that I could get feature vectors from a query image and find similar matches
