Bascially I want to detect an object and than track it in a video (frame-by-frame).
I can detect it on the first frame with for example ORB or SIFT. But for the next frames (or say next XX frames) I would like to avoid to calulcate again all the keypoints (ORB or SIFT) to detect it again.
Considering I want to track it in a video real time, what could I do ?
