We employ a nonlinear anisotropic diffusion operator like the ones used as a means of filtering and edge enhancement in image processing and in numerical methods for conservation laws. It turns out that algorithms currently used in image processing are very well suited for the design of nonlinear higher order dissipative terms. In particular, we stabilize(More)
