Solving Inverse Problems with Piecewise Linear Estimators: From Gaussian Mixture Models to Structured Sparsity
Guoshen Yu, Guillermo Sapiro, Stéphane Mallat
A general framework for solving image inverse problems is introduced in this paper. The approach is based on Gaussian mixture models, estimated via a computationally efficient MAP-…

Collaborative Hierarchical Sparse Modeling
Pablo Sprechmann, Ignacio Ramirez, Guillermo Sapiro +1
Sparse modeling is a powerful framework for data analysis and processing. Traditionally, encoding in this framework is done by solving an l_1-regularized linear regression problem,…
