A battle of three descriptors: SURF, FREAK and BRISK
Saved by uncleflo on August 27th, 2012.
I think developers and research guys who works with object recognition, image registration and other areas that uses keypoint extraction can find this post useful. Recently (from 2.4.2) a new feature descriptor algorithm was added to OpenCV library. FREAK descriptor is claimed to be superior to ORB and SURF descriptors, yet it's very fast (comparable to ORB). Also people in comments on my blog mentioned BRISK descriptor which is also new and more efficient than SURF. Well, finally i find a time to compare them and publish my research results.
