Journal ArticleDOI

Building robust wavelet estimators for multicomponent images using Stein's principle

TL;DR: The application of Stein's principle is applied to build a new estimator for arbitrary multichannel images embedded in additive Gaussian noise in order to exploit the correlations existing between the different spectral components.
Journal ArticleDOI

A SURE Approach for Digital Signal/Image Deconvolution Problems

TL;DR: The restoration problem is formulated as a nonlinear estimation problem leading to the minimization of a criterion derived from Stein's unbiased quadratic risk estimate and the deconvolution procedure is performed using any analysis and synthesis frames that can be overcomplete or not.
Journal ArticleDOI

Epigraphical projection and proximal tools for solving constrained convex optimization problems

TL;DR: In this article, a proximal approach is proposed to deal with a class of convex variational problems involving nonlinear constraints, which can be expressed as the lower-level set of a sum of a convex functions evaluated over different blocks of the linearly transformed signal.
Journal ArticleDOI

A Convex Approach for Image Restoration with Exact Poisson--Gaussian Likelihood

TL;DR: This work proposes a convex optimization strategy for the reconstruction of images degraded by a linear operator and corrupted with a mixed Poisson-Gaussian noise, and shows that in a variational framework the Shifted Poisson and Exponential approximations lead to very good restoration results.
