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. WebORB (Oriented FAST and Rotated BRIEF) descriptor is used to find matching keypoints. As a matching function we use number of matching features whose distance is below a given threshold.
