SYSTEM AND METHOD FOR REDUCTION OF BLOCK NOISE

摘要

A system and a method for block noise reduction are provided. The block noise reduction system (100) includes a feature value calculating unit (101 ), a filtering mode determining unit (102) and a filtering performing unit (103). The filtering performing unit (103) includes a two dimensional filtering performing unit (104), a direction determining unit (105) and a one dimensional filtering performing unit (106). The feature value calculating unit (101 ) calculates a feature value of a local texture with respect to an input pixel using pixel values of the input pixel and adjacent pixels.
