Discrete gradient methods in image processing

V. Grimm and G.R.W. Quispel

Abstract
In PDE-based image diffusion, gradient systems are widely used to denoise, regularise, and, in general, to enhance images. For these applications, preservation of the gradient structure in the discretisation is much more important than, for example, higher order of the integration scheme. We will discuss some results, that indicate, that discrete gradient methods can outperform standard methods in these applications.
