A low-power integrated smart sensor with on-chip real-time image processing capabilities

Abstract

A low-power, CMOS retina with real-time, pixel-level processing capabilities is presented. Features extraction and edge-enhancement are implemented with fully programmable 1D Gabor convolutions. An equivalent computation rate of 3 GOPS is obtained at the cost of very low-power consumption ( W per pixel), providing real-time performances ( microseconds for overall computation, ). Experimental results from the first realized prototype show a very good matching between measures and expected outputs
