CPU- and GPU-accelerated KinFu live 3d dense reconstruction algorithm has been included into opencv_contrib. It is time to learn how to match different descriptors. We know a great deal about feature detectors and descriptors. To solve that problem, OpenCV devs came up with a new "FREE" alternative to SIFT & SURF, and that is ORB. Specifically: Use the cv::xfeatures2d::SURF and its function cv::xfeatures2d::SURF::detect to perform the detection process; Use the function cv::drawKeypoints to draw the detected keypoints Vast Algorithms. ️ Change log is here.
