Blind deconvolution of images using optimal sparse representations

IEEE Trans Image Process. 2005 Jun;14(6):726-36. doi: 10.1109/tip.2005.847322.

Abstract

The relative Newton algorithm, previously proposed for quasi-maximum likelihood blind source separation and blind deconvolution of one-dimensional signals is generalized for blind deconvolution of images. Smooth approximation of the absolute value is used as the nonlinear term for sparse sources. In addition, we propose a method of sparsification, which allows blind deconvolution of arbitrary sources, and show how to find optimal sparsifying transformations by supervised learning.
