My task is to compare 2 pictures and tell if they are similar. First, I find the histograms of each image and compare them with a measure of similarity. Next, I compare the obtained distance with a certain threshold, if it is less than the threshold, then I calculate the AKAZE descriptor, filter by Hamming distance and RANSAC filter. then I check that after filtering the overlaps, there are more than 6 left, if more then I say that the images are similar. How do you approach my? Is he correct?
