基于流形的视频序列全景图的绘制方法

针对含动态场景的视频序列,本文提出了一种基于流形的全景图的绘制方法.该方法首先从视频序列中提取条形图,根据需要由一个或几个条形图组成图卡,利用相似测度确定图卡在流形种的次序;然后将相对应的图卡依最小代价路径按序排列在一起构成流形,完成全景图的拼接;最后利用拼接区域的相似性信息,使用基于局部金字塔的方法融合图像交叠处的颜色.实验结果表明,使用该方法得到的全景图可最大限度的保证原图像中的细节,没有严重的扭曲和变形,视觉效果比较好.

Manifold Method of Video Sequence Mosaic

This paper described an algorithm applied to the video sequence images mosaicing--manifold method, Firstly, strips were extracted in a video sequence, The charts were composed of some strips. The order that the chart was in the manifold was fixed by the similarity measure. Secondly, the corresponding charts between frames were connected and then mosaiced into a panoramic image according to optimized path. Finally, the image color of the ovedapping band was smoothed using the Laplacian Pyramid decomposition approach, The experiments show that the panoramic image mosaiced by the method preserves the detail of original image at the greatest degree and has the least cumulative visual errors and distortions. So the panoramic image has very good visual effect.
