摘要：
Global motion compensation coding is a novel coding method based on models. Its coding efficiency is higher than that of conventional coding method with motion compensation, so it is fit for very low bit-rate applications. But the key technology of global motion compensation coding is not solved well at present, such as global motion estimation, so global motion compensation coding is not applied widely in real-time applications. This paper focuses some research on key problems of global motion compensation coding to solve real-time global motion compensation coding. The new fast method of global motion estimation is proposed and is used in global motion compensation coding, thus the speed of global motion compensation coding is accelerated. Experimental results show that the speed of global motion compensation coding is improved compared with former method of global motion compensation coding.
