Claim 9:
10. The method according to claim 1, further comprising:
calculating a second degree of correlation between the first colour component and the second colour component corresponding to the spatial block for the spatial block;
shifting a Morton code of each point in the spatial block to right by N−1 bits to obtain two sub-spatial blocks if the second degree of correlation is less than a preset threshold of degree of correlation;
calculating a third degree of correlation between the first colour component and the second colour component corresponding to the two sub-spatial blocks;
constructing two sub-prediction models according to the two sub-spatial blocks if the third degree of correlation is greater than the second degree of correlation; and
obtaining the prediction value of the second colour component value of the encoding point by using the two sub-prediction models and the value of the first colour component.
