一种有效的视频序列拼接方法

An effective mosaic method of video sequence

针对视频序列拼接中容易造成拼接耗时较长、拼接效果不佳等问题,提出一种有效的视频序列拼接方法,首先,利用时域检测窗口对视频序列进行关键帧的提取,其次,利用相邻关键帧间特征点的匹配结合(random sample consensus)算法以及单应矩阵的级联特性,获取相邻关键帧和非相连关键帧间的匹配矩阵,最后通过融合实现了关键帧所表示的视频序列无缝拼接,效果比较理想。

In order to solve the problem of video mosaic such as time consuming,poor effect and so on,an effcetctive mosaic method of video sequence was proposed.Firstly,the keyframes were extracted using time domain detection window.Secondly,the matching matrixes of adjacent keyframes and the non-adjacent key frames were calculated using the adjacent keyframes features matching,RANSAC algorithm and the cascades of homography matrix.Finally,the seamless mosaic of video sequence represented by the keyframes was rendered by the image blending.The experiment demonstrates this method＇s efficient.
