Determining Optical Flow （Horn-Schunck光流）

WebOptical Flow Two Key Problems: 1. Determine what image property to track. 2. Determine how to track it Brightness constancy: Let’s track points of constant brightness, assuming that surface radiance is constant over time: I(x,y,t+1) = I(x−u 1,y −u 2,t) . Brightness constancy is often assumed by researchers, and often vio- WebUsing cv2.calcOpticalFlowFarneback (), which is a dense method, we get as output an ndarray ('flow' in below example) which contains the optical flow. … grand strand weather forecast
