  abstract = {A new multiscale method in surface processing is presented here which
	combines the image processing methodology based on nonlinear diffusion
	equations and the theory of geometric evolution problems. Its aim
	is to smooth discretized surfaces while simultaneously enhancing
	geometric features such as edges and corners. This is obtained by
	an anisotropic curvature evolution, where time is the multiscale
	parameter. Here, the diffusion tensor depends on the shape operator
	of the evolving surface. \par A spatial finite element discretization
	on arbitrary unstructured triangular meshes and a semi-implicit finite
	difference discretization in time are the building blocks of the
	easy to code algorithm presented here. The systems of linear equations
	in each timestep are solved by appropriate, preconditioned iterative
	solvers. Different applications underline the efficiency and flexibility
	of the presented type of surface processing tool.},
