SAMPLE ADAPTIVE FILTERING WITH OFFSETS

摘要

A method, a filtering control device, a computer program and a computer program product for processing a first picture in a sample adaptive filtering procedure are disclosed. The first picture is reconstructed from video data. The filtering control device obtains an offset magnitude from the video data. The offset magnitude indicates a magnitude of a sample adaptive offset to be applied in the sample adaptive filtering procedure. The filtering control device obtains an offset sign from the video data. The offset sign indicates a sign of the sample adaptive offset. The filtering control device determines the sample adaptive offset based on the offset magnitude and the offset sign. Moreover, the filtering control device processes, in the sample adaptive filtering procedure, at least a portion of the first picture while applying the sample adaptive offset.
