Optical flow lk
The Lucas–Kanade method assumes that the displacement of the image contents between two nearby instants (frames) is small and approximately constant within a neighborhood of the point under consideration. Thus the optical flow equation can be assumed to hold for all pixels within a window centered at . See more In computer vision, the Lucas–Kanade method is a widely used differential method for optical flow estimation developed by Bruce D. Lucas and Takeo Kanade. It assumes that the flow is essentially constant … See more The least-squares approach implicitly assumes that the errors in the image data have a Gaussian distribution with zero mean.
