An Augmented Lagrangian Approach to the Constrained Optimization Formulation of Imaging Inverse Problems
Manya V. Afonso, José M. Bioucas-Dias, Mário A. T. Figueiredo
We propose a new fast algorithm for solving one of the standard approaches to ill-posed linear inverse problems (IPLIP), where a (possibly non-smooth) regularizer is minimized unde…
Fast Image Recovery Using Variable Splitting and Constrained Optimization
Manya V. Afonso, José M. Bioucas-Dias, Mário A. T. Figueiredo
We propose a new fast algorithm for solving one of the standard formulations of image restoration and reconstruction which consists of an unconstrained optimization problem where t…
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…
