Abstract: A prediction method includes: performing downsampling on a luma component of a to-be-processed image block to obtain an initial signal of the luma component; obtaining a residual signal of the luma component based on the obtained initial signal of the luma component; obtaining a residual signal of a chroma component of the to-be-processed image block based on the chroma component of the to-be-processed image block without downsampling. The method further includes: respectively performing a transform on the residual signal of the luma component and the residual signal of the chroma component, to obtain transform coefficients, performing quantization on the obtained transform coefficients, to obtain quantization coefficients, and performing entropy encoding on the obtained quantization coefficients to obtain a bitstream.

Abstract: An image prediction method and apparatus is disclosed. The image prediction method includes: determining, according to information about adjacent image units adjacent to a to-be-processed image unit, whether a set of candidate prediction modes for the to-be-processed image unit includes an affine merge mode, where the affine merge mode indicates that respective predicted images of the to-be-processed image unit and the adjacent image units of the to-be-processed image unit are obtained by using a same affine model; parsing a bitstream to obtain first indication information; determining, in the set of candidate prediction modes, a prediction mode for the to-be-processed image unit according to the first indication information; and determining a predicted image of the to-be-processed image unit according to the prediction mode. The method reduces a bit rate of encoding a prediction mode, thereby improving encoding efficiency.
