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
