Hi guys,

Does OpenCV has any routines which would find keypoints on the depth images obtained from Kinect?

Most feature detectors find keypoints which are on edges/corners. Since those depth images are grayscale images (at least according to a fast google search), finding keypoints won't be a problem. If they are usable to the specific task you want to use them for is of course an entirely different question.
