摘要

我们提出了一项初步研究的结果，增强的图像，已被退化的小波编码算法。在这项初步研究中，我们测试了一组(非线性)图像增强算法。用一个简单的客观准则对结果进行了评价，发现它与小波退化图像的主观质量估计有合理的相关性。我们首先讨论了一些方面的有损小波编码和相关的退化。然后，我们简要概述了提出的质量措施。最后提出了经过上述退化后图像增强效果最优的后处理算法。

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 has been found to have reasonable correlation to subjective quality estimation for wavelet-degraded images. We first discuss some of the aspects of lossy wavelet coding and the associated degradation. Then we briefly outline the proposed quality measure. Finally we present the postprocessing algorithm which was found to be optimal for image enhancement after the abovementioned kind of degradation.
