Abstract:
A method and apparatus for video coding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a block in a current picture from a coded video bitstream. The prediction information includes an index for prediction offset associated with an affine model in an inter prediction mode. The affine model is used to transform between the block and a reference block in a reference picture that has been reconstructed. Further, the processing circuitry determines parameters of the affine model based on the index and a pre-defined mapping of indexes and offset values, and reconstructs at least a sample of the block according to the affine model.

Claim (Index 18):
The apparatus of  claim 15 , wherein the processing circuitry is configured to:\n change a second parameter of the affine model according to which of the plurality of offset values is associated with a second index of the plurality of indexes, the first and second parameters being two motion vector differences for two control points; determine motion vectors for the two control points based on the two motion vector differences; and derive a 4-parameter affine model based on the motion vectors of the two control points.
