WebORB is basically a fusion of FAST keypoint detector and BRIEF descriptor with many modifications to enhance the performance. First it use FAST to find keypoints, then apply Harris corner measure to find top N points among them. It also use pyramid to produce multiscale-features. But one problem is that, FAST doesn’t compute the orientation. WebAlthough, ORB and BRISK are the most efficient algorithms that can detect a huge amount of features, the matching time for such a large number of features prolongs the total image matching time. On the contrary, ORB(1000) and BRISK(1000) perform fastest image matching but their accuracy gets compromised. arawindak pelakorWebDec 2, 2024 · Now, we will use the ORB detector to extract the keypoints. First, we will create an ORB detector with the function cv2.ORB_create (). This function consists of a number of optional parameters. The most useful one is nfeatures which denotes the maximum number of features to be detected. baker katrina
