Summary:In this paper, coding efficiency improvement of HEVC using asymmetric motion partitioning (AMP) is provided based on HM-6.0. AMP allows asymmetric shape partition mode of prediction unit (PU) for inter prediction. AMP improves the coding efficiency, since irregular image patterns, which otherwise would be constrained to being represented by a smaller symmetric partition, can now be more efficiently represented without requiring further splitting. For encoder speed up, additional conditions are checked before doing motion estimation for each motion partitions. If the certain conditions are met, additional motion estimation, which is main source of encoder complexity for AMP, can be skipped. Experimental results demonstrate that AMP with encoding speed-up shows 0.8% coding efficiency improvement with 14% encoding time increase. Especially for videoconference sequences, coding efficiency improvement reaches to 1.4%.
