A Greedy Algorithm for the Analysis Transform Domain
Raja Giryes
Many image processing applications benefited remarkably from the theory of sparsity. One model of sparsity is the cosparse analysis one. It was shown that using l_1-minimization on…

Greedy Signal Space Methods for incoherence and beyond
Raja Giryes, Deanna Needell
Compressive sampling (CoSa) has provided many methods for signal recovery of signals compressible with respect to an orthonormal basis. However, modern applications have sparked th…
