New silicon results for the first VLSI vision circuit design following selective-change-driven (SCD) readout strategy are presented. Under this strategy, only pixels that exhibit large variations between the present and last transmitted illumination values are deemed to carry relevant information that is worth processing. A 32x32 pixel-matrix was designed and fabricated. In this paper, results of a tracking experiment are presented. The SCD embedded system designed exhibits much better per- formance on time resolution, bandwidth and processing power requirements than a traditional frame-based standard system.
