基于特征点匹配的视频分割算法研究

摘要

The continuous development of the Internet and digital technologies has put forward higher requirements on the security of digital media products.The video segmentation algorithm has been widely applied in video.In this thesis,by the method of analyzing the previous algorithms,an improved SIFT feature point for the video segmentation algorithm is established.It can detect the trimming of the lens accurately and realize the video segmentation.The validity of the algorithm is verified through experiements.%互联网和数字技术的不断发展,对数字媒体产品的安全性提出了更高要求,视频分割算法在视频领域得到了广泛应用.在分析以往算法的基础上,建立一种基于改进的SIFT特征点匹配的视频分割算法,可精确检测镜头切边,实现视频分割,并通过实验验证算法的有效性.
