WebThe by now well-known matching pursuit method of S. Mallat as well as the recently proposed orthogonal matching pursuit work purely sequential and are based on the idea of choosing only one single atom at a given time. Pursuing ideas which are related to modifications of the POCS method, we suggest a new type of orthogonalization …
