Cross-component sample offset edge direction derivations

A method of video encoding performed at a computing system having memory and one or more processors, the method comprising:

• receiving video data comprising a plurality of frames, including a current frame comprising a current block;
• determining an edge direction by performing edge detection for the current block;
• determining a difference between a current sample of the current block and a neighboring sample based on the edge direction;
• and
• applying a filter to the current block based on the determined difference.

A non-transitory computer-readable storage medium storing a video bitstream that is generated by a video encoding method, the video bitstream comprising:

• coded information for a plurality of blocks of video data, including a current block;
• and
• wherein the video encoding method comprises:
• determining an edge direction by performing edge detection for the current block;
• determining a difference between a current sample of the current block and a neighboring sample based on the edge direction;
• and
• applying a filter to the current block based on the determined difference.
