Proximal Splitting Methods in Signal Processing
Patrick L. Combettes, Jean-Christophe Pesquet
The proximity operator of a convex function is a natural extension of the notion of a projection operator onto a convex set. This tool, which plays a central role in the analysis a…
Parallel Proximal Algorithm for Image Restoration Using Hybrid Regularization -- Extended Version
Nelly Pustelnik, Caroline Chaux, Jean-Christophe Pesquet
Regularization approaches have demonstrated their effectiveness for solving ill-posed problems. However, in the context of variational restoration methods, a challenging question r…
An Iterative Method for Parallel MRI SENSE-based Reconstruction in the Wavelet Domain
Lotfi Chaari, Jean-Christophe Pesquet, Philippe Ciuciu +1
To reduce scanning time and/or improve spatial/temporal resolution in some MRI applications, parallel MRI (pMRI) acquisition techniques with multiple coils acquisition have emerged…
