Convex Parameter Estimation of Perturbed Multivariate Generalized Gaussian Distributions
Nora Ouzir, Frédéric Pascal, Jean-Christophe Pesquet
The multivariate generalized Gaussian distribution (MGGD), also known as the multivariate exponential power (MEP) distribution, is widely used in signal and image processing. Howev…
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…
A Hierarchical Bayesian Model for Frame Representation
L. Chaâri, J. -C. Pesquet, J. -Y. Tourneret +2
In many signal processing problems, it may be fruitful to represent the signal under study in a frame. If a probabilistic approach is adopted, it becomes then necessary to estimate…
A SURE Approach for Digital Signal/Image Deconvolution Problems
Jean-Christophe Pesquet, Amel Benazza-Benyahia, Caroline Chaux
In this paper, we are interested in the classical problem of restoring data degraded by a convolution and the addition of a white Gaussian noise. The originality of the proposed ap…
