Abstract
A method of decoding video data performed by an electronic device is provided. The method receives the video data and determines a block unit from a current frame included in the video data. The method further determines a plurality of neighboring sub-partitions selected from a plurality of neighboring sub-blocks and determines, from the current frame, more than one previously affine-coded block reconstructed in an affine-based mode prior to reconstructing the block unit. The method receives a plurality of neighboring motion vectors of the neighboring sub-partitions and a plurality of affine motion vectors of the affine-coded sub-blocks and derives a motion linear model based on the neighboring motion vectors and the neighboring positions of the neighboring sub-partitions and the affine motion vectors and the affine positions of the affine-coded sub-blocks. Then, the method determines a plurality of derived motion vectors based on the motion linear model for reconstructing the block unit.
