Title:
METHOD AND APPARATUS OF INHERITING SHARED CROSS-COMPONENT MODELS IN VIDEO CODING SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2024/093785
Kind Code:
A1
Abstract:
Method and apparatus for inheriting model parameters of a cross-component prediction mode. According to one method, a prediction candidate list comprising inherited cross-component prediction candidates is determined, wherein one or more default candidates are inserted into the prediction candidate list when a total number of candidates in the prediction candidate list is smaller than a maximum number. A target model parameter set associated with a target inherited prediction model is derived based on an inherited model parameter set associated with the target inherited prediction model selected from the prediction candidate list. According to another method, a prediction candidate list comprising one or more inherited cross-component prediction candidates is determined. One or more single mode prediction model candidates are derived from a multi-mode cross-component candidate and are included in the prediction candidate list.
