   Title:

   A narrow band method for the convex formulation of discrete multi-label
   problems.

   Abstract:

   We study a narrow band type algorithm to solve a discrete formulation
   of the convex relaxation of energy functionals with total variation
   regularization and non convex data terms. We prove that this algorithm
   converges to a local minimum of the original non linear optimization
   problem. We illustrate the algorithm with experiments for disparity
   computation in stereo and a multi-label segmentation problem and we
   check experimentally that the energy of the local minimum is very near
   to the energy of the global minimum obtained without the narrow band
   type method.
