Our next seminar will be given by Marion Foare, who will present on “Recent advances on solving the Mumford-Shah model for discrete images ”
Abstract-“Essential image processing and analysis tasks, such as image segmentation, simplification and denoising, can be conducted in a unified way by minimizing the Mumford-Shah functional. Although seductive, this minimization is in practice difficult because it requires to jointly define a sharp set of contours and a smooth version of the initial image. For this reason, various relaxations of the original formulations have been proposed, together with optimisation methods. In this talk, we propose several discrete approximations of the Mumford-Shah and their numerical resolution for image processing tasks. We compare the results with state-of-the-art convex relaxations of the Mumford–Shah functional, and show that the proposed methods lead to competitive denoising, restoration and segmentation results.“
