Epigraphical splitting for solving constrained convex formulations of inverse problems with proximal tools
Giovanni Chierchia, Nelly Pustelnik, Jean-Christophe Pesquet +1
We propose a proximal approach to deal with a class of convex variational problems involving nonlinear constraints. A large family of constraints, proven to be effective in the sol…

Spatio-temporal wavelet regularization for parallel MRI reconstruction: application to functional MRI
Lotfi Chaari, Sébastien Mériaux, Jean-Christophe Pesquet +1
Parallel MRI is a fast imaging technique that enables the acquisition of highly resolved images in space or/and in time. The performance of parallel imaging strongly depends on the…
