cv.jit.HSflow Estimates the optical flow using the Horn-Schunk method. Estimates the optical flow using the Horn-Schunk method. This technique assumes that changes in optical flow, over the image, are relatively uniform. It is slightly better at estimating faster movements that the Lucas-Kanade technique, but it will also become unreliable if the motion is too fast. It is better at finding the optical around contrast edges and returns generally cleaner results than Lucas-Kanade.
