Abstract
The present disclosure provides a method for decoding video data. The method comprises: obtaining a video block from a bitstream; obtaining neighboring luma and chroma sample values of the video block; performing at least one pre-operation to the neighboring luma sample values and to internal luma sample values in the video block, to obtain pre-operated neighboring and internal luma sample values, wherein performing the at least one pre-operation comprises calculating sample differences based on the neighboring and internal luma sample values; deriving a linear model by using the pre-operated neighboring luma sample values and the neighboring chroma sample values; predicting each of internal chroma sample values in the video block by applying the linear model to one or more corresponding pre-operated internal luma sample values for that internal chroma sample value; and obtaining decoded video block using the predicted internal chroma sample values.
