Modified explicit finite volume scheme for Perona-Malik equation

We propose modified explicit finite volume computational method for the numerical solution of the modified (in the sense of Catte, Lions, Morel and Coll) Perona-Malik nonlinear image selective smoothing equation (called anisotropic diffusion) in the image processing.

This access reduces the computational effort considerably, because we compute diffusion coefficients not in every scale step. Convergence of the method and numerical examples are presented.

 This is a joint work with Zuzana Kriva.
