-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…
Piecewise constant reconstruction of damaged color images
Riccardo Cristoferi, Irene Fonseca
A variational model for reconstruction of damaged color images is studied, in particular in the case where only finitely many colors are admissible for the reconstructed image. An…
A higher order model for image restoration: the one dimensional case
Gianni Dal Maso, Irene Fonseca, Giovanni Leoni +1
The one-dimensional version of the higher order total variation-based model for image restoration proposed by Chan, Marquina, and Mulet in [4] is analyzed. A suitable functional fr…
