Paper Abstract

This paper introduces a new algorithm for the restoration of black and white photographic images that have been distorted by linear blurs and additive noise. The algorithm is iterative and particularly efficient for one-dimensional causal distortions, such as motion blur, and one- and two-dimensional symmetric distortions, such as out-of-focus blurs. It involves solving sets of Toeplitz or block Toeplitz linear equations. The algorithm is illustrated using an example involving motion blur.
