Robust multichannel image restoration using Markov random field

Abstract

This paper addresses the problem of color image restoration, distorted by intra- and inter-channel blur, and coitupted by additive noise. The image is modeled as Markov random field, and color image restoration is cast as a maximum a Postion priori (MAP) estimation problem. We propose a first-order interchannel interaction model for restoration. We compare this model with the results when interaction is not considered. The proposed model is fairly general. and the result, are satisfactory even when interchannel degradation parameter is unknown.
