2015-05-12 11:54:16 -0600 | asked a question | Problem extracting descriptors of FAST opencv3 Hi everybody, I'm started to use openCV(3.0.0-dev) and now I'm trying different way to extract features from images (Fast, GoodFeaturesToTrack, Mser, Star, Sift, Surf). I started with SIFT and SURF and my code works good but now i'm tryng with FAST and i can't understand how extract descriptors of keypoints! For SIFT, for example, I used this code In des i have my descriptors and it's ok, but when I've tried with FAST I've obtained following error -> "OpenCV Error: The function/feature is not implemented () in detectAndCompute" I've noted that there is the method dectect() and I can extract keypoints but what about descriptors? Why it works for SIFT/SURF and not for FAST? How can I obtain the descriptors? Thank you for answer. |
