INTRA PREDICTION METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240107005 titled 'INTRA PREDICTION METHOD AND DEVICE
Simplified Explanation
The patent application describes an intra prediction method using a cross-component linear prediction mode (CCLM) for video coding. This method involves determining a luma block corresponding to a current chroma block, obtaining down-sampled luma reference samples based on available chroma reference samples, calculating linear model coefficients using the luma and chroma reference samples, and generating a prediction for the current chroma block based on the linear model coefficients and values of the down-sampled luma block.
