The main purpose of this paper is to show a domain decomposition with parallel and serial approaches for a nonlinear diffusion model used in the processing of digital images suggested by Barcelos, Boaventura and Silva Jr. [3], in addition to a multi-domain analysis for the evolution of this equation, which has as its main characteristic a balanced diffusion with a consequent preservation of boundaries. Some numerical results will be shown in order to illustrate the performance obtained in the model.
