Claim 0:
1. A prediction method, which is applied to an encoder and comprises:
determining a spatial block in which an encoding point is located;
constructing a prediction model according to the spatial block, wherein the prediction model is used for characterizing a predicted relationship between a first colour component and a second colour component of the encoding point;
acquiring a value of the first colour component and a value of the second colour component of the encoding point;
obtaining a prediction value of the second colour component of the encoding point by using the prediction model and the value of the first colour component;
calculating a difference between the value of the second colour component and the prediction value of the second colour component, and using the obtained difference as a residual of the encoding point; and
performing Level of Detail (LOD) partitioning and lifting transform based on the residual of the encoding point.
