  abstract = {We discuss methods which allow the fairing of discrete curves and
	surfaces. The primary objective is to retain and even enhance important
	features such as surface edges and corners. Two alternative approaches
	are presented. On the one hand an anisotropic geometric diffusion
	problem is discussed which respects edge features and in addition
	incorporates tangential smoothing along noisy edges. On the other
	hand we formulate an anisotropic energy, where the local energy integrand
	reflects detected geometric features. Furthermore new discretizations
	of anisotropic curve and surface evolution are presented.},
