Abstract:
Aspects of the disclosure provide methods and apparatuses for video decoding. In some examples, an apparatus includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information of a current block in a current picture from a coded video bitstream. The prediction information is indicative of an affine model in a merge mode. Further, the processing circuitry obtains, from a buffer, motion information of bottom locations in a neighboring block that is adjacent of the current block in the current picture. Then the processing circuitry determines, based on the motion information of the bottom locations in the neighboring block, parameters of the affine model that is used to transform between the block and a reference block in a reference picture that has been reconstructed. Further, the processing circuitry reconstructs at least a sample of the current block based on the affine model.

Claim (Index 1):
A method for video decoding in a decoder, comprising:\n decoding prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of an affine model in a merge mode; obtaining, from a buffer, motion information of bottom corner locations in a neighboring block that is adjacent to the current block in the current picture; determining motion vectors at control points of the current block based on the motion information of the bottom corner locations in the neighboring block; determining, based on the determined motion vectors at the control points of the current block, parameters of the affine model that is used to transform between the current block and a reference block in a reference picture that has been reconstructed; and reconstructing at least a sample of the current block based on the affine model.
