To use the matcher I compute keypoints and descriptors for the first image (img1) and then for each picture from the set, run the flann matcher comparing each of the images with img1 and get the best result.

WebORB is found to be least scale invariant. ORB(1000), BRISK(1000), and AKAZE are more rotation invariant than others. ORB and BRISK are generally more invariant to affine changes as compared to others. SIFT, KAZE, AKAZE, and BRISK have higher accuracy for image rotations as compared to the rest.
