Total variation, mean curvature flows, and an isoperimetric problem
Abstract: Total variation has become one of the most popular regularizers for image denoising and restoration, and has also been used as a basis for an algorithm for mean curvature motion. We shall present this algorithm (originally due to A. Chambolle) and we shall explore its connection with explicit solutions of the denoising problem, and with isoperimetric problems. We shall also relate it to a proof of convergence of the Almgren-Taylor-Wang scheme for crystalline mean curvature evolution of convex sets.| Zeit: | Freitag, 12.
