Optical Flow Method Optical Flow

Optical flow is a description of the motion information of image brightness. The optical flow method is initially proposed by Horn and Schunck in the 1981 , and the two-dimensional velocity field is creatively connected with the gray scale , which is introduced into the optical flow constrained equation to obtain the basic algorithm of the optical flow calculation. The optical flow calculation based on the motion of the object provides 2 hypotheses:The gray scale of the ① moving object remains u
