Hybrid Fast Search Algorithm Based on Multiview Video Coding
Yuan Mei-leng · Journal of Chinese Computer Systems · 2013
EPZS(Enhanced Predictive Zonal Search) is a fast hybrid motion vector search algorithm adopted by the motion estimation of Joint multiview video coding.EPZS algorithm is a predictive search algorithm but its search velocity is slow.For EPZS algorithm′s disadvantages,a fast hybrid search algorithm based on multiview video coding is proposed.The optimization is suggested mainly from the following four aspects: predictive vector sets,search model,threshold setting as well as search strategy.Experimental results on JMVC8.3 show that the performance of modified algorithm is so good that coding efficiency is also improved,on the promise of right code rate and reconstruction video quality comparing to EPZS in JMVC.The average encoding speed increased from 55.66 to 69.62 percent.
