AI Technical Summary
Current image encoding and decoding methods face challenges in efficiently handling high-resolution or high-quality images, particularly in determining optimal data units for compression and decompression, as existing methods do not effectively account for varying block sizes and shapes in chroma images.
The method involves hierarchically splitting luma and chroma images into coding units based on split shape modes, where the split shape mode considers the direction and type of blocks, and restricts splitting for chroma blocks below a certain size or area, determining coding units within these blocks.
This approach enhances the efficiency of image encoding and decoding by optimizing coding units based on block shapes and sizes, improving throughput and reducing computational complexity, especially for smaller chroma blocks.
