摘要: 利用MSDS定义块边界不连续度,并提出了一种新颖算法估计低频系数的量化误差使MSDS最小,从而有效地消除了块效应,并保持了图像的原有清晰度.

Abstract: We define the block boundary discontinuity measure as MSDS(mean squared difference of slopes).This paper presents a novel solution,which estimate the low frequency components to make the MSDS be its minimum,then the blocking effect can be efficiently reduced.

Key words: image processing, blocking effect, post-processing
