SIFT and SURF algorithms

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.

good, that you have said that! updated the answer with the right module name.

Actually, I am already using the opencv_contrib to perform face recognition, but thanks for the tip @ThorbjornSomod, and thanks for the answer @Vintez.
