Geometry Partition Blending Weights for Video Coding Efficiency

The patent applies preliminary action by pre-defining default motion candidates (such as zero motion vector candidates or affine merge candidates) that are automatically added to the motion candidate list when the list is not sufficiently populated. This advance preparation ensures that the candidate list is always complete without requiring complex runtime decisions, thereby improving coding efficiency while keeping the complexity manageable through standardized procedures.

The patent applies self-service by implementing a mechanism where the motion candidate list automatically fills itself with default candidates when it has fewer than the maximum allowed candidates. This self-completing behavior eliminates the need for external intervention or complex algorithms to generate sufficient candidates, thereby improving compression performance while minimizing the increase in computational complexity through a simple and efficient self-service approach.

The patent applies parameter changes by modifying the motion candidate list generation process to automatically include default candidates based on predefined parameters and conditions. This parameter-based approach ensures that the candidate list is always sufficiently populated without requiring manual intervention or complex operational procedures, thereby improving coding efficiency while maintaining ease of operation through standardized and predictable parameter-driven behavior.
