Abstract
A method and device for predicting colour component and a computer storage medium are provided. The method includes: acquiring at least one threshold value according to first colour component reconstructed values of all samples of a current coding block; performing grouping according to comparison results between a first colour component neighboring reference values of current coding block and the at least one threshold value to obtain at least two groups of first colour component neighboring reference values and second colour component neighboring reference values; establishing at least two computing models; selecting, according to comparison results between the first colour component reconstructed values and at least one threshold value, a computing model corresponding to each sample in current coding block from at least two computing models; and acquiring, according to the computing model corresponding to each sample, second colour component prediction values of all samples in the current coding block.
