TV denoising of two balls in the plane
Vicent Caselles, Matteo Novaga, Christiane Pöschl
The aim of this paper is to compute the explicit solution of the total variation denoising problem corresponding to the characteristic function of a set which is the union of two p…
Qualitative behavior for flux-saturated mechanisms: Traveling waves, waiting time and smoothing effects
Juan Calvo, Juan Campos, Vicent Caselles +2
This paper is devoted to the analysis of qualitative properties of flux-saturated type operators in dimension one. Specifically, we study regularity properties and smoothing effect…
A Contrario Selection of Optimal Partitions for Image Segmentation
Juan Cardelino, Vicent Caselles, Marcelo Bertalmio +1
We present a novel segmentation algorithm based on a hierarchical representation of images. The main contribution of this work is to explore the capabilities of the A Contrario rea…
Perimeter of sublevel sets in infinite dimensional spaces
Vicent Caselles, Alessandra Lunardi, Michele Miranda +1
We compare the perimeter measure with the Airault-Malliavin surface measure and we prove that all open convex subsets of abstract Wiener spaces have finite perimeter. By an explici…
