Document Type and Number:
WIPO Patent Application WO/2020/181428
Kind Code:
A1
Abstract:
Disclosed are a prediction method, an encoder, a decoder, and a computer storage medium. The method is applied to the encoder. The method comprises: creating a candidate list corresponding to a coding mode for the coding mode used by a coding block in an original image frame, wherein the coding mode comprises a first affine motion mode or a second affine motion mode, a reference block in the candidate list is spatially adjacent to the coding block, and the reference block is coded using the first affine motion mode or the second affine motion mode; performing affine motion estimation on the coding block according to the candidate list corresponding to the coding mode to obtain coding parameters corresponding to the coding block; and performing predictive coding on the coding block on the basis of the coding parameters corresponding to the coding block.
