A Majorize-Minimize subspace approach for l2-l0 image regularization
Emilie Chouzenoux, Anna Jezierska, Jean-Christophe Pesquet +1
In this work, we consider a class of differentiable criteria for sparse image computing problems, where a nonconvex regularization is applied to an arbitrary linear transform of th…
Noise Covariance Properties in Dual-Tree Wavelet Decompositions
Caroline Chaux, Jean-Christophe Pesquet, Laurent Duval
Dual-tree wavelet decompositions have recently gained much popularity, mainly due to their ability to provide an accurate directional analysis of images combined with a reduced red…
Primal-dual splitting algorithm for solving inclusions with mixtures of composite, Lipschitzian, and parallel-sum monotone operators
Patrick L. Combettes, Jean-Christophe Pesquet
We propose a primal-dual splitting algorithm for solving monotone inclusions involving a mixture of sums, linear compositions, and parallel sums of set-valued and Lipschitzian oper…
Relaxing Tight Frame Condition in Parallel Proximal Methods for Signal Restoration
Nelly Pustelnik, Jean-Christophe Pesquet, Caroline Chaux
A fruitful approach for solving signal deconvolution problems consists of resorting to a frame-based convex variational formulation. In this context, parallel proximal algorithms a…
4D Wavelet-Based Regularization for Parallel MRI Reconstruction: Impact on Subject and Group-Levels Statistical Sensitivity in fMRI
Lotfi Chaari, Sébastien Mériaux, Solveig Badillo +2
Parallel MRI is a fast imaging technique that enables the acquisition of highly resolved images in space. It relies on -space undersampling and multiple receiver coils with comp…
