Optical flow (OF) estimation aims at derive a motion-vector field that characterizes motions on a video sequence of images. In this paper, we propose a new multi-scale (or scale-space) algorithm that generates OF on cellular neural/non-linear network universal machine, a general purpose analog-VLSI hardware, at resolution of 128 × 128 with fair accuracy and working over a speed of 100 frames/s. The performance of the hardware implementation of the proposed algorithm is measured on a standard image sequence. As far as we are concerned, this is the first time when an OF estimator hardware is tested on a practical-size standard image sequence.
