OVERLAPPED BLOCK MOTION COMPENSATION USING TEMPORAL NEIGHBORS

摘要

Devices, systems and methods for digital video coding, which includes an overlapped block motion compensation (OBMC) process based on temporal neighbors, are described. An exemplary method for video processing includes generating, based on a weighted sum of at least two temporary prediction blocks, a prediction block for a current video block, a first of the at least two temporary prediction blocks being based on a first motion information associated with the current video block, a second of the at least two temporary prediction blocks being based on a second motion information associated with at least one neighboring block of the current video block, and the at least one neighboring block comprising a temporally neighboring block, and performing, based on the prediction block, a conversion between the current video block and a bitstream representation of the current video block.
