Abstract
A warp model is determined for a block to be coded by using local motion extension. Motion for an adjacent block is extended locally into the block to determine motion for predicting the block. A motion model used for inter-prediction of an adjacent block that shares at least a portion of a boundary with a current block to be predicted is determined. The motion model is a first translational motion vector or a first warp model. A second translational motion vector for inter-prediction of the current block is determined. A second warp model for the inter-prediction of the current block is determined using the motion model and the second translational motion vector. An inter-prediction process for the current block is performed using the second warp model. For example, the interprediction process may include determining a prediction block for encoding or decoding the current block.
