WebCreate an optical flow object for estimating the direction and speed of a moving object using the Horn-Schunck method. Use the object function estimateFlow to estimate the optical … The Horn–Schunck method of estimating optical flow is a global method which introduces a global constraint of smoothness to solve the aperture problem (see Optical Flow for further description). Ver mais The Horn-Schunck algorithm assumes smoothness in the flow over the whole image. Thus, it tries to minimize distortions in flow and prefers solutions which show more smoothness. The flow is … Ver mais • Lucas–Kanade method Ver mais Advantages of the Horn–Schunck algorithm include that it yields a high density of flow vectors, i.e. the flow information missing in inner parts of homogeneous objects is filled in from the motion boundaries.
