Abstract: The scene manifold can split the video sequence with static or dynamic scenes.The algorithm firstly constructs charts which orders could be found by the similarity measure，and then the video mosaics can be obtained by seeking the correct manifold cutting through the whole video.But for long video sequence，the algorithm has some limit on real time and hardware.This paper gives a new method for this problem.The long video is divided into several parts.For each section，the scene manifold algorithm is adopted to splitting all frames of video，and getting the panorama of this partition.The dynamic programming algorithm will be used to search the best seam-line between the adjacent panoramas obtained from previous step，and stitch the panoramas.The panorama of the whole video sequence could be obtained.The experiment result shows that the panorama image mosaiced using this method preserves the details at the greatest degree，and has the least cumulative visual errors，and can properly perform mosaics of real time in practical application.
