Abstract
An embodiment of the method receives input data associated with a current block in a current picture at a video encoder or receiving a video bitstream corresponding to compressed data including the current block in the current picture at a video decoder, wherein the current block is coded or to be coded in an affine mode according to an affine motion model; calculates and storing affine parameters for a plurality of coded blocks in the current picture; retrieves the affine parameters of one or more coded blocks from the temporal buffer; derives an affine candidate including affine motion vectors using the retrieved affine parameters of the neighboring block; and encodes or decodes the current block by predicting the current block using one or more motion compensated blocks by the derived affine candidate.
