一种基于块边界连续规则的后处理算法

Post-Processing Based on Block Boundary Discontinuity Criterion

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 。

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.
