An approach for encoding/decoding video data, performed by at least one processor, including: obtaining video data; parsing the obtained video data into blocks; generating a set of parameters of a current block, the set of parameters including at least block position information, motion vector information, and delta values; storing a subset of parameters included in the set of parameters in association with the current block; selecting a first warp model of the current block based on a subset of parameters; and decoding the video data based on the first warp model.
