Abstract
A method is disclosed for selecting a reference sample for deriving a cross-component relation model in intra prediction. In the disclosed embodiments, a video decoding device derives temporary sampling positions from neighboring samples of the current block by using characteristics of a reconstructed luma component or neighboring samples of the current block. The video decoding device evaluates and adjusts the temporary sampling positions to select final positions and derives the cross-component relation model by using samples of the final positions. The video decoding device generates chroma prediction values of the chroma component by applying the cross-component relation model to the luma component.
