Abstract
Systems and methods for encoding and decoding using warp motion modes are provided. A method includes receiving a bitstream that includes a coded picture; obtaining a plurality of motion vectors pointing to positions in neighboring blocks that are adjacent to a current block in the coded picture, the plurality of motion vectors including at least one temporal motion vector; obtaining motion samples for a warp model based on the plurality of motion vectors; and decoding the current block by using the warp model and the motion samples including the at least one temporal motion vector for prediction. Some Embodiments may include methods of using temporal motion information to derive a warp model, and may further provide warp sample selection and grouping. Some embodiments may provide improvements on local warp motion modes.
