Does anybody know of any practical applications using Carver Mead's artificial retinas ? Are there any new papers published about the project - I only have one paper from the Neurocomputing book (eds Anderson & Rosenfeld). Thanks, Suran Goonatilake Dept. of Computer Science University College London Gower St. London WC1E 6BT Uk.

The Mahowald Retina from Mead's group at CIT makes an exceedingly useful "front-end" for other visual chips (such as motion detectors, etc.) It allows a chip to be active over a large interval of brightnesses at one time. >Are there any new papers published >about the project - I only have one paper from the Neurocomputing >book (eds Anderson & Rosenfeld). I am not sure, but I do know that other groups are working on reducing the complexity of the circuitry. One group at Hopkins is creating a retina based on 2-transistor current-conveyors instead of the 5-transistor transconductance amplifier. By reducing the size and complexity of the retinal circuit, more visual processing "back-end" circuitry can be put on the chip for a given pixel density. -Thoams Edwards
