Opencv fast orb

WebORB stands for Oriented FAST and rotated BRIEF. In 2011, Opencv labs developed ORB which was an amazing alternative to SIFT and SURF. It’s faster and has less computation cost. Unlike SIFT and SURF, it is not patented. ORB makes use of a modified version of the FAST keypoint detector and BRIEF descriptor.
