Abstract

Inspired by a visual multi-sensitive model for the vertebrate retina, by using signal processing tools, a two-dimensional CMOS VLSI chip, extracting the appropriate properties of the scene, is designed and then successfully tested. Depending on the internal parameters, this prototype of an early vision system is sensitive to edges, contrasts and motion. Subthreshold analog VLSI techniques have been used to design this low-power and fast silicon retina. Tests on the chip and its simulations results are emphasized
