"One of the central issues in the field of sparse representations is the design of overcomplete dictionaries with a fixed sparsity level from a given dataset. This article describes a fast and efficient procedure for the design of such dictionaries. The method implements the following ideas: a reduction technique is applied to the initial dataset to speed up the upcoming procedure; the actual training procedure runs a more sophisticated iterative expanding procedure based on K-SVD steps. Numerical experiments on image data show the effectiveness of the proposed design strategy."^^ . "2012" . . "IEEE"^^ . . "IEEE"^^ . . . . . . . . "Cristian"^^ . "Rusu"^^ . "Cristian Rusu"^^ . . . .
