为了建立一种通用、鲁棒的镜头边界检测算法,根据镜头转换的特性和多种视频特征融合的思想,选取了YUV直方图特征、纹理特征和边缘特征进行特征融合并计算帧间差值,采用全局阈值与自适应阈值相结合的方法,对镜头边界检测加以控制,提高阈值选取的准确性。实验结果表明,该算法能够有效地实现视频镜头边界检测,并对闪光、字幕有着较强的鲁棒性。

A general and robust shot boundary detection algorithm was established. According to characteristics of lens con- version and the ideal of multiple video features fusion, a shot boundary detection algorithm was proposed based on YUV histo- gram, texture feature and edge orientation histogram. The global threshold was combined with self- adaptive threshold so as to control the process of shot boundary detection and enhance the accuracy of threshold selection. The experiment results show that the algorithm can effectively realize video s...
