INTRA PREDICTION DEVICE AND METHOD INVOLVING MATRIX-BASED INTRA PREDICTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18220646 titled 'INTRA PREDICTION DEVICE AND METHOD INVOLVING MATRIX-BASED INTRA PREDICTION
Simplified Explanation
The patent application describes an image decoding method that involves obtaining image information from a bitstream, deriving transform coefficients, generating residual and prediction samples, and generating reconstructed samples for a current block.
- The method involves obtaining image information from a bitstream, which includes residual information and prediction-related information.
- Transform coefficients are derived based on the residual information.
- Residual samples for a current block are generated based on the transform coefficients.
- An intra prediction mode for the current block is derived based on the prediction-related information.
- Prediction samples for the current block are generated based on the intra prediction mode.
- Reconstructed samples for the current block are generated based on the prediction samples and the residual samples.
- The image information includes flag information that determines whether the intra prediction mode type for the current block is a matrix-based intra prediction (MIP).
- If the flag information indicates MIP, the intra prediction mode type for the current block is determined as MIP.
- The prediction samples for the current block are generated based on MIP samples.
