Abstract:

Motion estimation and motion compensation plays a key part in electronic image stabilization system. In order to improve performance of motion estimation and to reduce the burden of computer for real time application, this paper presents a new global motion estimation algorithm called step global motion estimation based on macro block algorithm (SGMEMB). It also develops the motion estimation and motion compensation skeleton, which is used in electronic image stabilization system, on which the stable image sequence by using a new two step motion compensation algorithm (TSMC) is obteined. The simulation results show that the method applied to electronic image stabilization system is efficient and feasible.

Key words: global motion estimation, local motion estimation, motion compensation, electronic image stabilization
