Abstract
Prediction information of a current block in a current picture is decoded from a coded video bitstream, where the prediction information indicates that the current block is to be predicted based on an affine model. A plurality of affine motion parameters of the affine model is derived via affine bilateral matching in which the affine model is derived based on reference blocks in a first reference picture and a second reference picture of the current picture. The plurality of affine motion parameters is not included in the coded video bitstream. Control point motion vectors of the affine model are determined based on the derived plurality of affine motion parameters. The current block is reconstructed based on the derived affine model.
