A Fast Algorithm for the Constrained Formulation of Compressive Image Reconstruction and Other Linear Inverse Problems
Manya V. Afonso, Jose M. Bioucas-Dias, Mario A. T. Figueiredo
Ill-posed linear inverse problems (ILIP), such as restoration and reconstruction, are a core topic of signal/image processing. A standard approach to deal with ILIP uses a constrai…
Fast Frame-Based Image Deconvolution Using Variable Splitting and Constrained Optimization
Mario A. T. Figueiredo, Jose M. Bioucas-Dias, Manya V. Afonso
We propose a new fast algorithm for solving one of the standard formulations of frame-based image deconvolution: an unconstrained optimization problem, involving an data-f…
A Variable Splitting Augmented Lagrangian Approach to Linear Spectral Unmixing
Jose Bioucas-Dias
This paper presents a new linear hyperspectral unmixing method of the minimum volume class, termed \emph{simplex identification via split augmented Lagrangian} (SISAL). Following C…
