Abstract
Methods and apparatuses for performing cross-component intra prediction, including: receiving a current chroma block from a coded bitstream; determining, from the coded bitstream, that a scaling factor used for the current chroma block in a chroma for luma (CfL) intra prediction mode; deriving a predicted scaling factor based on first neighboring samples of the current chroma block and second neighboring samples of a luma block that is co-located with the current chroma block; using the predicted scaling factor as the scaling factor used for the current chroma block in the CfL intra prediction mode; reconstructing the current chroma block after scaling the current chroma block based on the predicted scaling factor.
