Abstract
Techniques for performing sample adaptive offset (SAO) and adaptive loop filter (ALF) processes in a video coding process are described. The SAO and ALF processes may be combined. In one example, the determination of offset values for a SAO filter process may be based on classifications used in an ALF process. In one example, an ALF classification that indicates a particular directional characteristic of a video block may be used to determine how and whether an SAO filter process is applied to each sample within the video block.
