Class for computing the LATCH descriptor
LATCH is a binary descriptor based on learned comparisons of triplets of image patches.
Note: the descriptor can be coupled with any keypoint extractor. The only
demand is that if you use set RotationInvariance = True then you will
have to use an extractor which estimates the patch orientation (in
degrees). Examples for such extractors are cv.ORB and cv.SIFT.
