Title: OFFSETS AT SUB-PIXEL RESOLUTION
Abstract:
This disclosure describes techniques applied during video encoding and decoding processes. In one example, a method of encoding video data comprises calculating a plurality of offset values for a coded unit of the video data, wherein the offset values are associated with a plurality of different integer and sub-integer pixel locations, applying the offset values to predictive video blocks to generate offset predictive video blocks, and encoding video blocks of the coded unit based on the offset predictive video blocks. In another example, a method of decoding video data comprises receiving a plurality of offset values for a coded unit of the video data, wherein the offset values are associated with a plurality of different integer and sub-integer pixel locations, applying the offset values to predictive video blocks to generate offset predictive video blocks, and decoding video blocks of the coded unit based on the offset predictive video blocks.
