Semi-local Total Variation for Regularization of Inverse Problems
Résumé
We propose the discrete semi-local total variation (SLTV) as a new regularization for inverse problems in imaging. We show that the corresponding optimization problems can be efficiently solved by a primal-dual algorithm, which is easy to implement. The SLTV favors piecewise linear images, so that the main drawback of the total variation, its clustering effect, is avoided.
