A new Lattice Boltzmann method for a Gray–Scott based model applied to image restoration and contrast enhancement

Abstract

The aim of this work is to propose a new numerical approach to image restoration and contrast enhancement based on a reaction-diffusion model (Gray–Scott model). For noise removal, a Lattice Boltzmann technique is used. This method is usually used in fluid dynamics experiments. Since pixels motion can be compared to fluids motion, the presented technique also indicates a good performance in processing noisy images. The efficiency and performance of the proposed algorithm are verified by several numerical experiments.
