INTRA PREDICTION-BASED IMAGE CODING METHOD AND DEVICE USING MPM LIST - A simplified explanation of the abstract
This abstract first appeared for US patent application 18377577 titled 'INTRA PREDICTION-BASED IMAGE CODING METHOD AND DEVICE USING MPM LIST
Simplified Explanation
The image decoding method described in the abstract involves deriving intra prediction modes for blocks in an image based on candidate modes from neighboring blocks, generating prediction samples and a restoration picture for the current block, and selecting the final intra prediction mode based on certain conditions.
- Derives left and upper modes as candidate intra prediction modes for the current block.
- Constructs an MPM list using the left and upper modes.
- Derives the final intra prediction mode for the current block from the MPM list.
- Generates prediction samples and a restoration picture based on the selected intra prediction mode.
- Selects the left or upper mode as the final intra prediction mode if certain conditions are met.
