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 (1.5 µW per pixel), providing real-time performances (50 microseconds for overall computation, 0.5 GOPs/mW). Experimental results from the first realized prototype show a very good matching between measures and expected outputs.
