WebApr 4, 2016 · lucas kanade computes a very sparse flow. So there will be many points in your map-as-in-dense-flow for which you dont have a flow information. You must decide what kind of values you will put to those pixel. – Micka Apr 4, 2016 at 12:40 1 WebImplement Lucas-Kanade optical flow estimation, and test it for the two-frame data sets provided in Python from scratch
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 .
