Optical flow or optic flow is the pattern of apparent motion of objects, surfaces, and edges in a visual scene caused by the relative motion between an observer (an eye or a camera) and the scene.
Lots of resources say that there are two types optical flow algorithms. And Lucas-Kanade is a sparse technique, but I …
