摘要： A method for video encoding is provided, comprising partitioning a frame of video data into a plurality of blocks; obtaining a current prediction of a current block of the plurality of blocks using one or more motion vectors of the current block; obtaining one or more collocated predictions of the current block using one or more motion vectors of one or more neighbor blocks of the current block in respective one or more blending areas, wherein each of the one or more blending areas is at least part of the current block and adjustable based at least on the partitioning; and obtaining a combined prediction of the current block by combing the current prediction with the one or more collocated predictions.

摘要： The present disclosure relates to a method for video coding. The method includes obtaining a first reference picture and a second reference picture associated with a current prediction block, obtaining a first prediction L0 based on a first motion vector MVO from the current prediction block to a reference block in the first reference picture, obtaining a second prediction L1 based on a second motion vector MV1 from the current prediction block to a reference block in the second reference picture, determining whether a bidirectional optical flow (BDOF) operation is applied, and calculating a bi-prediction of the current prediction block based on the first prediction L0 and the second prediction L1, and first gradient values and second gradient values.
