Abstract
A method and apparatus for video coding system that utilizes low-latency template-matching motion-vector refinement are disclosed. According to this method, a current template for a current block is determined, where the current template includes an inside current template including inside prediction samples or inside partially reconstructed samples inside the current block. The inside partially reconstructed samples are derived by adding a DC value of the current block to the inside prediction samples. Corresponding candidate reference templates associated with the current block are determined at a set of candidate locations. A location of a target reference template among the candidate reference templates that achieves a best match between the current template and the candidate reference templates is determined. An initial motion vector (MV) is then refined according to the location of the target reference template.
