If conventional intra prediction methods are used, then the processing is straightforward, but coding effectiveness is limited
Solution Approach 1:
The patent applies filtering to reference samples before intra prediction, preparing enhanced reference data in advance. This preliminary filtering improves prediction accuracy by removing noise and enhancing relevant features in the reference samples
Solution Approach 2:
The patent inherits model parameters from previously coded blocks and reuses them for current block prediction. This copying of proven parameters from adjacent blocks improves prediction accuracy while reducing the need to recalculate parameters from scratch
3Productivity
If filter-based prediction is applied to improve coding efficiency, then coding effectiveness improves, but computational complexity increases
Solution Approach 1:
The patent changes the prediction approach by applying filters to reference samples and inheriting model parameters, transforming the conventional prediction process into a more efficient filter-based system that improves coding efficiency
Solution Approach 2:
The patent enables the decoding process to inherit and reuse model parameters from previously decoded blocks, allowing the system to serve itself by utilizing already processed information rather than requiring complete reprocessing
