Systems and methods for loop filtering for multi-view coding

A computing system, comprising:

• control circuitry;
• memory;
• and
• one or more sets of instructions stored in the memory and configured for execution by the control circuitry, the one or more sets of instructions comprising instructions for:
• receiving video data comprising a plurality of pictures, wherein the plurality of pictures includes a first picture corresponding to a first view and a second picture corresponding to a second view;
• determining whether loop filtering parameters for the first picture corresponding to the first view and the second picture corresponding to the second view are to be signaled jointly or separately;
• and
• when the loop filtering parameters are to be signaled jointly, signaling a first indicator in a multi-view video bitstream, the first indicator indicating that the loop filtering parameters are signaled jointly for the first picture and the second picture, wherein the first indicator indicates that a shared set of loop filtering parameters are signaled jointly, and wherein a second set of loop filtering parameters are signaled separately for the first picture.

A method of generating a video bitstream, the method comprising:

• obtaining a multi-view video bitstream, including:
• receiving video data comprising a plurality of pictures, wherein the plurality of pictures includes a first picture corresponding to a first view and a second picture corresponding to a second view;
• determining whether loop filtering parameters for the first picture corresponding to the first view and the second picture corresponding to the second view are to be signaled jointly or separately;
• and
• when the loop filtering parameters are to be signaled jointly, signaling a first indicator in a multi-view video bitstream, the first indicator indicating that the loop filtering parameters are signaled jointly for the first picture and the second picture, wherein the first indicator indicates that a shared set of loop filtering parameters are signaled jointly, and wherein a second set of loop filtering parameters are signaled separately for the first picture;
• and
• transmitting the video bitstream, including the first indicator.
