Sample Adaptive Offset (SAO) has been adopted asa new in-loop filtering block in High Efficiency Video Coding(HEVC). It can significantly increase compression efficiencyespecially for sequences that contain computer graphics contentup to 23%. To get the optimum SAO parameters, exhaustiveoperations are required because of the huge amount of sampleswhich the encoder has to study. In this work, a low...
HEVC has adopted Sample Adaptive Offset (SAO) as a new in-loop filtering block. SAO can significantly improve coding efficiency, however, it requires exhaustive operations in order to calculate best SAO parameters for each Coding Tree Unit (CTU). SAO parameters estimation process takes around 93 % of the overall SAO execution time which depends on number of candidate SAO modes. Real time and low power...
