Abstract: Recently, model-based studies of morpho-genesis employing computer simulations have begun to attract much attention in mathematical biology. Mor-phogenesis can be described and modeled mathemati-cally by reaction-diffusion system. We proposed a Digi-tal Reaction-Diffusion System (DRDS) — a model of a discrete-time discrete-space reaction-diffusion system for nonlinear signal processing tasks. Example applications include enhancement and restoration of fingerprint im-ages as well as generation of biological textures for com-puter graphics applications. In this paper, we present the design of a special DRDS that emulates characteris-tic behavior of excitable dynamics, and demonstrate its application to a shortest path search problem. 1
