Evaluation of postprocessing stages for wavelet-compressed image enhancement based on a simple perceptual criteria

We present the results of a preliminary study of enhancement of images that have been degraded by lossy wavelet coding algorithms. In this preliminary study we tested a large set of (nonlinear) image enhancement algorithms. The results have been evaluated using a simple objective criterion, which ha...
