L-Shaped Video Block Partitioning for Better Compression Efficiency

The video block is divided into multiple partitions including L-shaped partitions, allowing the partitioning to follow the actual shape of objects within the block rather than forcing them into traditional square or rectangular shapes. This segmentation approach enables better alignment with object boundaries, improving compression efficiency by reducing residual errors at object edges.

The patent introduces asymmetric L-shaped partitions that better match the natural shapes of objects in video content. Instead of using symmetric square or rectangular partitions, the L-shaped partitions can adapt to object contours, providing a more accurate representation of object boundaries and improving compression performance.

The patent applies L-shaped partitioning selectively in regions where it provides benefit, rather than uniformly across the entire video block. By allowing L-shaped partitions only where they improve compression efficiency and using traditional partitions elsewhere, the computational complexity is managed while still achieving improved compression performance in critical regions.

The patent implements L-shaped partitioning as an optional enhancement rather than a mandatory requirement for all blocks. By applying this technique partially to only those blocks where it provides significant benefit, the overall computational complexity increase is minimized while still achieving improved compression efficiency where needed.
