Abstract:

This document considers the problem of reconstructing an image from a noisy record. It describes methods due to Geman and Geman 1984 and Besag 1986 which use a Markov random field model for the true scene but assume that each pixel consists of a single colour. In order to improve the quality of the restoration at the boundary of regions of different colours the authors extend these methods to allow pixels to contain two regions of colour separated by a single straight line. An algorithm for performing the reconstruction is presented and illustrated by an example. Keywords Split pixels, Restoration algorithms.
