So i am currently working on converting an opencv program in c++ to java to do 2d feature matching. I've been having trouble understanding what some of the lines are doing and how i might be able to find their java equivalent, any help would be appreciated thanks!
// Calculate the ORB descriptor based on the keypoint
Ptr<Feature2D> orb_feat = ORB::create();
Mat descriptors;
orb_feat->compute(input, keypoints, descriptors);
