Using the bootstrap resampling technique, it is demonstrated that uncertainty in the estimates of parameters in image models directly affects uncertainty in the image restorations themselves. Two resampling algorithms are developed which quantify this parameter uncertainty and use the information to improve the image quality. Real and artificial data were employed in numerical examples, and some unexpected results were obtained for the cross-validation choice of smoothing parameter.
