On the linear convergence rates of exchange and continuous methods for total variation minimization

Axel Flinth, Frédéric de Gournay, Pierre Weiss

We analyze an exchange algorithm for the numerical solution total-variation regularized inverse problems over the space M() of Radon measures on a subset of R d. Our main re…

A scalable estimator of sets of integral operators

Valentin Debarnot, Paul Escande, Pierre Weiss

We propose a scalable method to find a subspace of low-rank tensors that simultaneously approximates a set of integral operators. The method can be seen as…

Simple mechanical cues could explain adipose tissue morphology

Diane Peurichard, Fanny Delebecque, Anne Lorsignol +5

The mechanisms by which organs acquire their functional structure and realize its maintenance (or homeostasis) over time are still largely unknown. In this paper, we investigate th…

Multiview Attenuation Estimation and Correction

Valentin Debarnot, Jonas Kahn, Pierre Weiss

Measuring attenuation coefficients is a fundamental problem that can be solved with diverse techniques such as X-ray or optical tomography and lidar. We propose a novel approach ba…

A projection algorithm on measures sets

Nicolas Chauffert, Philippe Ciuciu, Jonas Kahn +1

We consider the problem of projecting a probability measure on a set of Radon measures. The projection is defined as a solution of the following variational pr…

Compressed sensing with structured sparsity and structured acquisition

Claire Boyer, Jérémie Bigot, Pierre Weiss

Compressed Sensing (CS) is an appealing framework for applications such as Magnetic Resonance Imaging (MRI). However, up-to-date, the sensing schemes suggested by CS theories are m…
