Convergence and Stability of a Fractional Differential System in Image Processing
Abstract
The Perona-Malik differential equation (PMDE) is an important model in image processing. In this paper, we present a numerical scheme for the fractional form of anisotropic nonlinear PMDE with initial-boundary conditions. The stability and convergence of this scheme is verified. Finally, some numerical experiments are given for denoising, enhancing and blurring the images.
