Abstract
Several techniques for performing digital image restoration are reviewed and the problems associated with evaluating image processing are discussed. An application of constrained deconvolution to images of the liver [human] produced by single-photon emission computed tomography is presented. Specific evaluation criteria are suggested and based on these, the choice of conditions best suited for processing liver images is proposed. Typically cold tumor contrast can be improved by a factor of greater than 2 while image mottle increases negligibly.
