Abstract

The analysis of time-varying image sequences is a classical problem of machine vision (Aggarwal & Nandhakumar, 1988; Ullman, 1979), but is likely to be very useful in robotics, passive navigation and several other fields. Two major approaches have been proposed for the analysis of image sequences: one based on differential techniques aims at computing a dense optical flow, and the other recovers the displacement of selected tokens on the images, by tracking tokens from one image to the next one.
