摘要:
The present disclosure relates to overlapped block motion compensation with derived motion from neighbors. A method for video processing, comprising: determining, during a conversion between a current block of visual media data and a corresponding coded representation of the visual media data, at least one neighboring block for the current block; determining motion information of the at least one neighboring block; and performing Overlapped Block Motion Compensation (OBMC) for the current block based on the motion information of the at least one neighboring block, wherein the OBMC includes using an intermediate prediction values of one sub-block of the current block and a prediction values of at least one neighboring sub-block to generating a final prediction values of the sub-block.
