Abstract

A decoder receives, from a bitstream, an indication of a block vector, a residual of a current block, an indication of an affine transform, and affine transform parameters. The decoder determines, based on the indication of the block vector, a reference block in a same picture as the current block for predicting the current block. The decoder applies, based on the indication of the affine transform, the affine transform parameters to the reference block to generate an affine transformation of the reference block. The decoder decodes the current block based on the residual and the affine transformation of the reference block.
