Paper of the Day (Po’D): Fast Orthogonal Sparse Approximation Algorithms over Local Dictionaries Edition

Hello, and welcome to Paper of the Day (Po’D): Fast Orthogonal Sparse Approximation Algorithms over Local Dictionaries Edition. In the forthcoming weeks, I am preparing for the first part of my scientific mission at INRIA in Rennes, France (details to come). Today’s paper is co-authored by members of INRIA and IRISA in Rennes: B. Mailhé, R. Gribonval, P. Vandergheynst and F. Bimbot, “Fast Orthogonal Sparse Approximation Algorithms over Local Dictionaries,” Signal Processing, http://dx.doi.org/10.1016/j.sigpro.2011.01.004 (this paper appears in a forthcoming special issue of Signal Processing on “Advances in Multirate Filter Bank Structures and Multiscale Representations.”)
