Abstract

We extend the MRF image model commonly employed in the Bayesian development of image segmentation procedures to include a degradation channel resulting in a 2D hidden Markov model as the basis for the segmentation problem. We solve the segmentation problem by deriving the expectation-maximization algorithm for the case where the 'hidden' Markov source is the 2-D MRF that generates a true scene and the degradation channel is an additive, memoryless, grey-level degradation process that produces the observed scene.
