长视频序列拼接

针对长视频序列的全景图拼接，提出了一种新的处理方法。该方法将长视频序列分段，对每一段分别采用场景流形算法进行拼接;将拼接后的相邻图像采用动态规划的思想搜索最佳缝合线;依次缝合所有拼接后的图像，得到整个视频序列的全景图。实验结果表明，采用该方法拼接而成的全景图可以最大限度地保证源图像的细节，没有明显的扭曲和变形，视觉效果比较好。在实际应用中，该方法可以较好地实现含动态场景的长视频序列的全景图拼接。

Mosaic of long video sequence

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 dy- namic programming algorithm will be used to search the best seam-line between the adjacent panoramas obtained from previ- ous 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 cu- mulative visual errors,and can properly perform mosaics of real time in practical application
