Original Abstract Submitted
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.
