Abstract

We propose gradient-based algorithm for local velocity estimation that uses a Gabor-type filter as a spatial pre-filtering stage. An integrated differentiation and division circuit extracts the local image velocity in continuous time. We describe the design, implementation and the simulation results of a 1-D velocity sensor consisting of 27 pixels. Each pixel generates two outputs: the local image velocity and the local motion direction.
