VMVW01 - Variational methods, new optimisation techniques and new fast numerical algorithms

In this joint work with T. Pock (TU Graz, Austria) we present a relaxation of line energies which depend on the curvature, such as the elastica functional, introduced in particular to complete contours in image inpainting problems. Our relaxation is convex and tight on C^2 curves.
