The OpenCV library provides the SIFT (Scale-invariant feature transform) and SURF (Speeded Up Robust Features) algorithms? If so, where can I find it?
Note: I know the algorithms are patented in US.
Thanks in advance
Yes both are implemented in OpenCV. You can find them in the opencv-contrib modules under the section xfeatures2d.
The module is xfeatures2d :) Just making sure there is no confusion. Also if SURF/SIFT is the only functions you are interested in I would suggest only generating the xfeatures2d module (and not any other modules from opencv_contrib) as some of the other modules are corrupted.
Actually, I am already using the opencv_contrib to perform face recognition, but thanks for the tip @ThorbjornSomod, and thanks for the answer @Vintez.
