Luttrell S P, December 1989, A Bayesian derivation of an iterative autofocus/super-resolution algorithm, RSRE technical report (Malvern, UK), 4337
We derive an estimate-maximise (EM) formulation of a Bayesian super-resolution algorithm for reconstructing scattering cross sections from coherent images - this renders obsolete all past attempts to derive such a scheme. We extend the analysis to the case of simultaneous super-resolution and autofocussing, which corrects the damage caused by an uncertain point spread function. Finally, we demonstrate our method by presenting the results of some simple numerical experiments.
