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.
