    Abstract: The present invention relates to the performance of motion vector refinement in a search space for multi-reference inter-prediction. Two or more reference pictures are selected, one of those used for motion vector refinement. Based on an initial estimate of a motion vector to the reference picture for motion vector refinement, a search space in this reference image is constructed. Using template matching, the first motion vector is refined. The second motion vector to another reference picture is calculated using its initial estimate, the initial estimate of the first motion vector and the refined first motion vector.

  • Publication number: 20250184523
    Abstract: An apparatus and method are provided for inter prediction of a current geometric partition of a coding block. When the coding block is enabled for a geometric partition merge mode, a merge candidate list for the coding block partitioned into two geometric partitions including the current geometric partition is generated. The merge candidate list generation comprises deriving one or more spatial merge candidates from neighboring coding units, and directly or immediately deriving one or more temporal motion vector predictions (MVPs). An uni-prediction MV is derived as a motion vector of the current geometric partition based on the merge candidate list. The current geometric partition of the coding block is predicted based on the uni-prediction MV to obtain a predicted value of the current geometric partition.

    Abstract: The present disclosure relates to motion vector refinement. As a first step, an initial motion vector and a template for the block are obtained. Then, the refinement of the initial motion vector is determined by template matching with said template in a search space. The search space is located on a position given by the initial motion vector and includes one or more fractional sample positions, wherein each of the fractional sample positions belonging to the search space is obtained by interpolation filtering with a filter of a predefined tap-size assessing integer samples only within a window, said window being formed by integer samples accessible for the template matching in said search space.
