The time redundancy in video sequences can be eliminated by motion estimation. Block matching is a popular motion estimation method, adopted by all video codec standards.
视频编码通过运动估计消除时间冗余信息，块匹配方法是目前所有视频编码标准采用的运动估计方法。

Experimental results for many video sequences show that the method can eliminate high frequency tremble, remain active motion of camera and realize real time image stabilization satisfactorily.
实验结果说明该方法可以较好地去除高频抖动，保留摄像机的主动运动，实现实时稳像。

Image offset method that is also fast can be applied to motion compensation, time-frequency method is intuitionistic and have a better accurate, which is applied extensively on offline.
