Abstract

A first motion vector and a second motion vector are determined for a first block in a current picture of a video, where the first motion vector is indicative of a first reference block in a first picture, and the second motion vector is indicative of a second reference block in a second picture. A bilateral template is generated based on a weighted combination of the first reference block and the second reference block. A refined first motion vector is determined based on the bilateral template and a first set of reference blocks in the first picture. A refined second motion vector is determined based on the bilateral template and a second set of reference blocks in the second picture. Prediction information of the first block is generated according to (i) the refined first motion vector, (ii) the refined second motion vector, and (iii) a final motion compensation interpolation filter.
