Abstract
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 syntax element for a multi-hypothesis cross-component prediction (MH-CCP) mode. The syntax element indicates whether to reconstruct a first chroma sample of the current coding block by combining a set of luma samples including a first luma sample based on a model having a plurality of model parameters. When the MH-CCP mode is enabled, a computing system determines a first subset of model parameters and a second subset of model parameters used in the MH-CCP mode for the current coding block successively. The computing system combines the first luma sample and a set of neighboring luma samples using the plurality of model parameters to generate the first chroma sample, and reconstructs the current coding block including the first chroma sample.
