ABSTRACT
<p><b>Abstract</b>—Geman and Reynolds [<ref rid="bibi06577" type="bib">7</ref>] present an approach to linear image restoration which provides for recovery of horizontal and vertical gray-level discontinuities from blurred and noisy observations. We extend their model and parameter selection method to include diagonal discontinuities. A hazard of this modeling approach is identified and addressed. We also comment on the truncated Gibbs sampler suggested in the paper [<ref rid="bibi06577" type="bib">7</ref>].</p>
INDEX TERMS
Statistical image reconstruction, discontinuity recovery, parameter selection, Gibbs sampler, Metropolis algorithm, simulated annealing.
