During the visit of Gabriele Steidl, new solutions for restoration problems involving images corrupted with Poisson noise have been devised. The idea is to employ an Anscombe based approximation which allows the variational problem to be formulated as a constrained convex optimization problem. The constraint is addressed through a novel […]

Prasad Tetali (Georgia Institute of Technology, Atlanta) has been invited for a one month visit during the academic year 2011-2012. He worked with N. Gozlan, C. Roberto (Univ. Paris 10) and P.-M. Samson on optimal transport and its link with the Ricci curvature on discrete spaces. In Riemannian geometry, this […]
