Abstract : This work aims at comparing several state-of-the-art methods for cosparse signal recovery, in the context of sound source localization. We assess the performance of ve cosparse recovery algorithms: Greedy Analysis Structured Pursuit, l1 and joint l1,2 minimization, Structured Analysis Iterative Hard Thresholding and Structured Analysis Hard Thresholding Pursuit. In addition, we evaluate the performance of these methods against the sparse synthesis paradigm, solved with corresponding joint l1,2 minimization method. For this evaluation, the chosen applicative showcase is sound source localization from simulated measurements of the acoustic pressure eld.
