Artificial retinas — fast, versatile image processors

Abstract

Artificial retinas combine video camera and image processing functions, allowing machines to function in their environment with unprecedented autonomy, or to augment quality control, surveillance and hazard monitoring. We review several retina devices and reveal how they execute basic manipulations of the image at processing speeds well beyond the capabilities of the human eye.
