基于边缘模型的数字图像后处理方法研究

On Digital Image Post-Processing Algorithms of Model-Based Edge

基于边缘模型重建的数字图像后处理算法可以改善高倍压缩图像的主观和客观质量。文章通过对压缩图像退化原因以及现有的基于边缘模型的后处理算法的分析和讨论,提出了一种新的基于边缘模型的后处理算法及今后数字图像后处理算法的研究方向。

The subjective and objective quality of decompressed images can be improved by digital image post-processing algorithms of model-based edge. In this paper,the writer represents a new post-processing algorithms of model-based edge and the research tendency in the area of post-processing by analysing the reason of image degradation and the available algorithms.
