What are the advantages of integer transformation?
43. HEVC - SAO
http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=6324411
The concept of SAO is to reduce mean sample distortion of a region by first classifying the region samples
into multiple categories with selected classifier, obtaining an offset for each category, and then addig the offset
to each sample of the category, where the classifier index and the offset of the region are coded in the
bitstream.
