摘要：
Accuracy of prediction block (PB) plays a very important role in improving the coding performance. In this paper, we propose tagged multi-hypothesis motion compensation scheme (TMHMC) for inter frames to improve the accuracy of PB. TMHMC not only makes use of temporal correlation between frames but also the spatial correlation as motion vectors of adjacent blocks are used to derive the PB. For entropy coding process, only one motion vector and a tag indicating which adjacent block is used are coded in bit-stream. Adding TMHMC scheme as an additional mode in MPEG internet video coding (IVC) platform, the bitrate saving is up to 12% at the same objective quality compared with anchor. Average bitrate saving is close to 6% over all test sequences. In addition, we also implement the conventional multi-hypothesis motion compensation (MHMC) scheme. 3% bitrate is further saved on average by TMHMC compared with conventional MHMC.
