BFMatcher refers to a Brute-force matcher that is nothing, but a distance computation used to match the descriptor of one feature from the first set with each of the other features in the second set. The nearest is then returned.

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.
