We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Mumford-Shah functional as $\Gamma$-limit of discrete Perona-Malik energies
Massimiliano Morini and Matteo Negri
Abstract
We prove that a suitable rescaling of biased Perona-Malik energies, defined in the discrete setting, $\Gamma$-converges to an anisotropic version of the Mumford-Shah functional. Numerical results are discussed.
