Summary:This article describes a method for image restoration using sparse representations. A sparse representation is a description of an image in the form of fragments of coefficients selected from a predefined dictionary. This paper presents a general approach to image restoration using sparse representation and pre-prepared experimental results for a simple implementation of this convention.
