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. FAST features are not scale-invariant ... WebORB는 다른 특징점 추출 알고리즘과는 다르게 OpenCV 연구소에서 개발되었습니다. 특허권이 걸린 SIFT와 SURF를 대신할 수 있는데, 계산비용과 매칭 속도가 더 좋다고 합니다.
