Abstract
A method of video decoding, apparatuses and non-transitory computer-readable storage media thereof are provided. The method of video decoding includes obtaining a first parameter based on a first neighbor block of a current block; obtaining a second parameter based on the first neighbor block and/or a second neighbor block of the current block; constructing an affine model using the first parameter and the second parameter; and obtaining a control point motion vector (CPMV) for the current block based on the affine model. The first neighbor block and the second neighbor block are obtained from a plurality of neighbor blocks to the current block based on at least one scanning area and at least one scanning distance. The first neighbor block and the second neighbor block are obtained by scanning the at least one scanning area at the at least one scanning distance.
