Abstract:
Method and apparatus of video coding using decoder derived motion information based on bilateral matching or template matching are disclosed. According to one method, an initial motion vector (MV) index is signalled in a video bitstream at an encoder side or determined from the video bitstream at a decoder side. A selected MV is then derived using bilateral matching, template matching or both to refine an initial MV associated with the initial MV index. In another method, when both MVs for list  0  and list  1  exist in template matching, the smallest-cost MV between the two MVs may be used for uni-prediction template matching if the cost is lower than the bi-prediction template matching. According to yet another method, the refinement of the MV search is dependent on the block size. According to yet another method, merge candidate MV pair is always used for bilateral matching or template matching.

Claim (Index 21):
An apparatus for video coding using motion compensation, the apparatus comprising one or more electronic circuits or processors arranged to:\n receive input data associated with a current block in a current picture; determine a best starting motion vector (MV) pair for a bilateral matching merge mode or best starting motion vectors (MVs) for individual lists of a template matching merge mode; refine the best starting MV pair to a refined MV pair for the bilateral matching merge mode or the best starting MVs to refined MVs for the individual lists of the template matching merge mode by search within a search window around the best starting MV pair or the best starting MVs; determine a final MV or a final motion vector predictor (MVP) from a set of MV candidates or MVP candidates including a selected MV related to the refined MV pair or the refined MVs; and encode or decode the current block or a current MV of the current block using the final MV or the final motion vector predictor (MVP) at an encoder side or a decoder side respectively.
