Sparse representation of images using learned dictionaries have been shown to work well
for applications like image denoising, impainting, image compression, etc. In this paper …

Based on conventional matching pursuit (MP) algorithm, an improved approach of MP is
presented in this paper. By introducing a new strategy of building complete library, the …

Time-frequency atom decomposition (TFAD) provides a flexible representation for non-
stationary signals, but the extremely high computational effort greatly blocks its practical …
