Dyadic partition-based training schemes for TV/TGV denoising
Elisa Davoli, Rita Ferreira, Irene Fonseca +1
Due to their ability to handle discontinuous images while having a well-understood behavior, regularizations with total variation (TV) and total generalized variation (TGV) are som…
Vector Field Models for Nematic Disclinations
Amit Acharya, Irene Fonseca, Likhit Ganedi +1
In this paper, a model for defects that was introduced in \cite{ZANV} is studied. In the literature, the setting of most models for defects is the function space SBV (special bound…
Homogenization and Phase Separation with Fixed Wells -- The Supercritical Case
Riccardo Cristoferi, Irene Fonseca, Likhit Ganedi
A variational model for the interaction between homogenization and phase separation is considered in the regime where the former happens at a finer scale than the latter. The first…
Homogenization and phase separation with space dependent wells -- The subcritical case
Riccardo Cristoferi, Irene Fonseca, Likhit Ganedi
A variational model for the interaction between homogenization and phase separation is considered. The focus is on the regime where the latter happens at a smaller scale than the f…
-Convergence of an Ambrosio-Tortorelli approximation scheme for image segmentation
Irene Fonseca, Lisa Maria Kreusser, Carola-Bibiane Schönlieb +1
Given an image , the aim of minimising the Mumford-Shah functional is to find a decomposition of the image domain into sub-domains and a piecewise smooth approximation of…
Anisotropic Surface Tensions for Phase Transitions in Periodic Media
Rustum Choksi, Irene Fonseca, Jessica Lin +1
This paper establishes bounds on the homogenized surface tension for a heterogeneous Allen-Cahn energy functional in a periodic medium. The approach is based on relating the homoge…
