  • An adaptive global motion estimation algorithm is proposed in this article. Based on the statistic feature of block matching moving vector, the method calculates the basic translation vector between current frame and referenced frame through a revisable parameter, and adaptively chooses processing algorithm for image sources with different characteristics. Simulation results show that the proposed algorithm not only has the ad-vantages of low complication, short delay and simple implementation, but also can highly improve the coding efficiency when PSNR varies slightly.
