Abstract
Various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current image frame and a first syntax element. The first syntax element has a first predefined value that indicates that the band offset only mode is enabled to determine a first sample offset of a first color sample based on luma samples, independently of any associated luma gradient of the luma samples. When the band offset only mode is enabled, quantized values are generated based on the luma samples including a first luma sample collocated with the first color sample. A first color sample is classified based on the quantized values to determine the first sample offset of the first color sample. The current image frame is reconstructed at least by adjusting the first color sample based on the first sample offset.
