A Micropower Centroiding Vision Processor

Abstract

A biologically-inspired hybrid vision chip is pre- sented for real-time object-based processing for tasks such as centroiding, sizing and counting of enclosed objects. This system presents the first silicon retina capable of centroiding and sizing multiple objects in true parallel fashion. Based on a novel dis- tributed algorithm, this approach uses the input image to enclose a feedback loop to realize a data-driven pulsating action. The sensor provides a resolution of 48 48 pixels with a 85 m
