%X An automatic composition algorithm for sports video in same scene is proposed. First, the information of the foreground areas in current frame is obtained with global motion estimation and image registration between current frame and temporally adjacent frames, Then ,the spatial relationship between the two pre-composition frames is obtained by using global motion estimation method. Finally, the composition frame is constructed based on the information of the foreground areas of both pre-composition frames. Experiments demonstrate that proposed method is robust to the dynamic scene and able to compose the sports video keeping both of the foreground areas of pre-composition frames clear.
