Abstract
Methods, apparatuses, and non-transitory computer-readable storage mediums are provided for decoding a video block in geometry partition mode (GPM). The method may include partitioning the video block into first and second geometric partitions. The method may include obtaining a first motion vector refinement (MVR) for the first geometric partition. The method may include obtaining a second MVR for the second geometric partition. The method may include obtaining a candidate list that comprises a plurality of motion vectors (MVs). The method may include obtaining a first MV from the candidate list for the first geometric partition. The method may include obtaining a second MV from the candidate list for the second geometric partition. The method may include calculating a third MV by adding the first MV with the first MVR for the first geometric partition. The method may include calculating a fourth MV. The method may include obtaining prediction samples.
