Abstract (en)

[origin: WO2019072373A1] The present disclosure relates to motion vector determination and refinement. In particular, a refined motion vector is determined based on initial motion vector using template matching in a certain search space around the initial motion vector. The template is determined based on the samples pointed to by the initial motion vectors. The template is then updated based on the refined motion vector determined and used to further refine the motion vectors. This may be performed iteratively.
