Given a signal S ∈ RN and a full-rank matrix D ∈ RN×L with N , we define the signal's overcomplete representations as all α ∈ RL satisfying S = Dα. Among all the possible solutions, we have special interest in the sparsest one--the one minimizing ||α||o. Previous work has established that a representation is unique if it is sparse enough, requiring ||α||o o
