使用线性分割和序列合并的视频镜头分割方法

摘要

This paper proposed a video bidirectional frame distance model based on bidirectional frame distance comparison , using linear traversal method and low threshold to roughly segment the video into sets of fragment sequence and set of boundary se -quence .Then by comparing the fragments aside the boundary sequence ,the roughly segmented fragments are combined into video shots ,with which we achieved the linear method for both abrupt change and gradual change shot transition .%本文提出一种双向帧距离模型，基于帧距离双向对比，采用较低的全局阈值，使用线性遍历的方法对视频内容进行粗镜头划分成碎片序列集合和边界序列集合。然后通过比对每一个边界序列相邻的碎片序列内容的相似度，对粗划分的内容进行再合并，从而实现了用线性方法同时解决突变类镜头切换和渐变类镜头切换的镜头分割问题。
