Abstract
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding 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. 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, and determines parameters of the affine model that is used to transform between the block and a reference block in a reference picture based on the motion information of the bottom locations in the neighboring block. Further, the processing circuitry reconstructs samples of the current block based on the affine model.
