Constrained Anisotropic Diffusion and some Applications (bibtex)
by Gabriele Facciolo, Federico Lecumberry, Andres Almansa, Alvaro Pardo, Vicent Caselles, Bernard Rouge
Abstract:
Minimal surface regularization has been used in several applications ranging from stereo to image segmentation, sometimes hidden as a graph-cut dis- crete formulation, or as a strictly convex approximation to TV minimization. In this paper we consider a modified version of minimal surface regulariza- tion coupled with a robust data fitting term for interpolation purposes, where the corresponding evolution equation is constrained to diffuse only along the isophotes of a given image u and we design a convergent numerical scheme to accomplish this. To illustrate the usefulness of our approach, we apply this framework to the digital elevationmodel interpolation and to constrained vector probability diffusion.
