Intra-Frame Prediction and Decoding Methods and Apparatuses for Image Signal - A simplified explanation of the abstract
This abstract first appeared for US patent application 18536562 titled 'Intra-Frame Prediction and Decoding Methods and Apparatuses for Image Signal
The abstract of this patent application describes an intra-frame decoding method for video streams that involves obtaining prediction mode information for a signal component of a block, determining the prediction mode of the signal component, obtaining a predicted value for a sampling point of the signal component, and obtaining a reconstructed value for the sampling point based on the predicted value.
- Prediction mode information is obtained for a signal component of a block from a video code stream.
- The prediction mode of the signal component is determined from a set that includes linear model above (LMA) and linear model left (LML) modes.
- A predicted value for a sampling point of the signal component is obtained.
- A reconstructed value for the sampling point is obtained based on the predicted value.
