Systems and methods for blending inter-intra predictions

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 blocks, including a first block that is partitioned into a first section and a second section, from a video bitstream;
• identifying a prediction mode for the first block from a syntax element of the video bitstream;
• in accordance with the prediction mode being a partition-based inter-intra prediction mode, wherein the first section is associated with an inter prediction mode and the second section is associated with an intra prediction mode, blending the first section of the first block using a first blending mask and the second section of the first block using a second blending mask, the second blending mask being different than the first blending mask;
• and
• decoding the first block using the blended first and second sections.

A non-transitory computer-readable storage medium storing one or more sets of instructions configured for execution by a computing device having control circuitry and memory, the one or more sets of instructions comprising instructions for:

• receiving video data comprising a plurality of blocks, including a first block that is partitioned into a first section and a second section, from a video bitstream;
• identifying a prediction mode for the first block from a syntax element of the video bitstream;
• in accordance with the prediction mode being a partition-based inter-intra prediction mode, wherein the first section is associated with an inter prediction mode and the second section is associated with an intra prediction mode, blending the first section of the first block using a first blending mask and the second section of the first block using a second blending mask, the second blending mask being different than the first blending mask;
• and
