Paper Abstract

In this paper, different types of mutihypothesis techniques are studied. Based on the transform domain multihypothesis provided in redundant discrete wavelet transform (RDWT), other multihypothesis methods, such as spatial domain or temporal domain multihypothesis are added to improve the performance of a single multihypothesis scheme. Experimental results show that combining two types of multihypothesis motion compensation (MHMC) is promising. Choosing wisely, combining three MHMC methods is possible to get a gain. But as more and more multihypothesis involved, the room of improvement is getting smaller and smaller. At the same time, the increasement of the overhead burden also limits the gain of adding more hypothesis. Also the limitation of combining MHMC techniques along with the vector burden are discussed.
