Target identification has been an active researching area in past decades. In this paper, we present an iteration procedure to optimize the size of the undercomplete dictionary when multiple undercomplete dictionaries are used to characterize the scattering signatures of a complex target. Furthermore, we extend the signature reconstruction and decision criterion with only single undercomplete dictionary...
Matching pursuit (MP) is an iterative algorithm for signal representation which is applied widely to compression, feature extraction, signal denoising, and more. During last decades, main attention about the algorithm has been focused on the signal decomposition with respect to a complete or overcomplete dictionary. However, in this paper, we extend results by Mallat and Zhang about MP with overcomplete...
