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 a syntax element for a cross-component intra prediction (CCIP) mode. The CCIP mode indicates whether each chroma sample of the current coding block is determined based on one or more luma samples. An electronic device generates a plurality of hypothesis values to be used in predicting a first chroma sample by combining a plurality of neighboring luma samples of a first luma sample that is co-located with the first chroma sample using a plurality of coefficients. The first chroma sample is predicted by combining the first luma sample and the plurality of hypothesis values based on a plurality of weighing factors. The electronic device reconstructs the current coding block including the first chroma sample.
