VERFAHREN UND VORRICHTUNG ZUR BILDVERBESSERUNG FÜR VIDEOKOMPRESSION MIT NIEDRIGER BITRATE

摘要

A method and apparatus for deblocking and edge enhancement of block based digital video includes determining that two blocks share a common boundary; measuring edge activity of the common boundary, comparing the measured edge activity to a first threshold, filtering one or more pixels of the two blocks with a low pass filter if the edge activity is below the first threshold, and enhancing one or more pixels of the two neighboring blocks if the edge activity is at or above the first threshold.
