Abstract

In a method for video decoding in a decoder, a first motion vector and a second motion vector for a first block in a current picture are received. 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 and a refined second motion vector are determined based on the bilateral template, reference blocks in the first picture and reference blocks in the second picture respectively. An initial motion vector of a second block that is ceded after the first block is determined according to at least one of the first motion vector and the second motion vector for the first block.
