Abstract

Complex signals need to be adaptively expanded over families of waveforms selected to match their different structures. A matching pursuit is a greedy algorithm that expands signals over vectors that are selected among redundant dictionaries of waveforms. The properties of this algorithm are reviewed. Applications to sound and image processing with dictionaries of time- frequency atoms are described.
