+This matcher trains cv::flann::Index on a train descriptor collection and calls its nearest search
 methods to find the best matches. So, this matcher may be faster when matching a large train
 collection than the brute force matcher. FlannBasedMatcher does not support masking permissible
 matches of descriptor sets because flann::Index does not support this. :
