Abstract: Image processing technology is a popular practical technology and has important research value for many areas. In this work, and in order to improve the quality of images, we propose to modify the classical Perona-Malik model, by replacing the integer differential operator (ordinary derivative) with the fractional differential operator. The numerical resolution of the proposed model is based on the finite difference method, we analyse efficient numerical methods for this fractional model, and we give practical experiments with natural images which have been corrupted by Gaussian noise . ...
