The basic rate of change of image brightness equation constrains the optical flow velocity. The velocity (u.v) has to lie along a line perpendicular to the brightness gradient vector (Ex, E,). The distance of this line from the origin equals E, divided by the magnitude of (E,, E,). We cannot, however, determine the …

Opencv horn schunck

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.
