摘要
A new anisotropic diffusion model is proposed for image denoising, which is based on reaction-diffusion systems with p(x)-growth. By Galerkin's method, we establish the existence and uniqueness of weak solutions of the system for Neumann boundary conditions. Experimental results illustrate the effectiveness of the model in image restoration. (c) 2011 Elsevier Ltd. All rights reserved.
