Original Abstract Submitted
The various implementations described herein include methods and systems for coding video. In one aspect, a video bitstream includes a current coding block of an image frame and signals a first syntax element for a multi-hypothesis cross-component prediction (MH-CCP) mode. A computing system determines that the MH-CCP mode is enabled to reconstruct each of a plurality of chroma samples of the current coding block based on a respective luma sample collocated with the respective chroma sample and one or more neighboring luma samples. The computing device identifies a five tap model configured to determine chroma samples of the current coding block in the MH-CCP mode. Based on the five tap model, a pair of neighboring luma samples of a first luma sample is identified to generate a first chroma sample collocated with the first luma sample. The computing system reconstructs the current coding block including the first chroma sample.
