Image Halftoning with Turing Patterns

Atsushi Nomura

Abstract

This paper presents an image halftoning algorithm with a reaction-diffusion system in which periodic patterns called Turing patterns autonomously emerge. Image halftoning refers to conversion of a gray level image to a binary image so that the human visual system can perceive the original gray level image from the converted binary one. The reaction-diffusion system has activator and inhibitor distributions, and creates the Turing type periodic patterns in the distributions from an initial noisy distributions under the condition of long-range inhibition. Characteristics of the Turing patterns depend on a parameter of the reaction-diffusion system. Thus, by modulating the parameter distribution according to an image brightness distribution, the proposed algorithm creates Turing patterns of which characteristics distribute spatially; the human visual system can perceive distribution of the Turing patterns as the original image. Application of the proposed algorithm to a test image demonstrates its qualitative performance and convergence.
