TL;DR

It is established here that the EB condition is both sufficient and necessary for replacing an l/sub 0/ optimization by linear programming minimization when searching for the unique sparse representation.

Abstract

In previous work, Elad and Bruckstein (EB) have provided a sufficient condition for replacing an l/sub 0/ optimization by linear programming minimization when searching for the unique sparse representation. We establish here that the EB condition is both sufficient and necessary.
