IMAGE SEGMENTATION METHOD AND APPARATUS FOR IMAGE ENCODING AND DECODING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240129464 titled 'IMAGE SEGMENTATION METHOD AND APPARATUS FOR IMAGE ENCODING AND DECODING

Simplified Explanation

The image decoding method described in the abstract involves determining coding blocks, obtaining split shape mode information from a bitstream, determining split modes for the coding blocks, and decoding color components based on the split modes.

• Determining coding blocks and split shape mode information:

 - The method involves identifying a first coding block and a second coding block corresponding to the first block.
 - When the size of the first coding block is equal to or smaller than a preset size, split shape mode information is obtained from a bitstream.

• Determining split modes and decoding color components:

 - The split mode of the first coding block is determined based on the first split shape mode information.
 - The split mode of the second coding block is determined based on the second split shape mode information.
 - Coding blocks of different color components are decoded based on the split modes of the respective coding blocks.

Potential Applications

This technology can be applied in image and video processing systems, compression algorithms, and multimedia applications.

Problems Solved

This method helps in efficiently decoding images by determining split modes for coding blocks, which can improve the overall decoding process and image quality.

Benefits

- Improved image decoding efficiency - Enhanced image quality - Better compression performance

Potential Commercial Applications

- Video streaming services - Image editing software - Multimedia compression tools

Possible Prior Art

One possible prior art could be existing image and video decoding methods that may not involve split shape mode information for determining split modes of coding blocks.

=== What are the specific preset sizes used for determining split shape mode information? The abstract does not specify the exact preset sizes used for determining split shape mode information.

=== How does the method handle errors or inconsistencies in the split shape mode information obtained from the bitstream? The abstract does not mention how the method handles errors or inconsistencies in the split shape mode information obtained from the bitstream.
