Homotopy based algorithms for -regularized least-squares

Charles Soussen, Jérôme Idier, Junbo Duan +1

Sparse signal restoration is usually formulated as the minimization of a quadratic cost function , where A is a dictionary and x is an unknown sparse vector. It is we…

Enhanced sampling schemes for MCMC based blind Bernoulli-Gaussian deconvolution

D. Ge, J. Idier, E. Le Carpentier

This paper proposes and compares two new sampling schemes for sparse deconvolution using a Bernoulli-Gaussian model. To tackle such a deconvolution problem in a blind and unsupervi…

On Algorithms Based on Joint Estimation of Currents and Contrast in Microwave Tomography

Paul-André Barrière, Jérôme Idier, Yves Goussard +1

This paper deals with improvements to the contrast source inversion method which is widely used in microwave tomography. First, the method is reviewed and weaknesses of both the cr…
