Abstract

This paper is intended to develop an LSI that restores in real time an image pattern with defects and contamination. To this end, based on the principle of shape formation in biological bodies, a reaction-diffusion model that can generate and repair Turing patterns, such as stripes and spots seen in fingerprint and body marks, is proposed. A parallel architecture of the reaction-diffusion chips incorporating this model is presented. By means of circuit simulation, it is shown that this LSI can restore stripe (spot) patterns.
