VIDEO ENCODER, VIDEO DECODER, AND CORRESPONDING ENCODING AND DECODING METHODS

Abstract: techniques are described of a linear model prediction mode. a set of reconstructed neighboring luma samples are determined. two pairs of luma value and chroma value are determined according to n reconstructed neighboring luma samples, n reconstructed neighboring chroma samples, m reconstructed neighboring luma samples, and m reconstructed neighboring chroma samples. the minimum value of the n reconstructed neighboring luma samples is not less than the maximum luma value of the remaining reconstructed neighboring luma samples of the set of reconstructed neighboring luma samples. the maximum value of the m reconstructed neighboring luma samples is not larger than the minimum luma value of the remaining reconstructed neighboring luma samples of the set of reconstructed neighboring luma samples. m>1 and n>1. linear model parameters are determined based on the two pairs of luma value and chroma value, and a predictive block is determined based on the linear model parameters.
