This paper presents a global motion estimation method for diving video.Human body color model is constructed base on the athletes' simple dress in diving video and the area of human body within the foreground and background is picked up so as to improve the efficiency of global motion estimation.Meanwhile

the adjacent frame difference and the direction of the reference module are used to remove the modules which not used in the global motion estimation

so module-matching time is reduced accordingly.Experimental results show that the presented method can not merely reduce the computational complexity of the global motion estimation’s

but also improve its accuracy.
