Abstract:
Usage for History-based affine parameters is described. In an exemplary aspect, a method for video processing includes deriving, for a conversion between a current block of video and a bitstream representation of the current block, affine related information associated with affine model for the current block based on affine parameters stored in a buffer for storing affine related information of blocks coded prior the current block; and performing the conversion by using the affine related information.
