This paper present a simple shot detection method, video brightness information is used to detect abrupt shot and the combination of brightness and chroma information is used to detection.
本文提出了一种简单的镜头检测方法，该方法首先使用视频亮度信息检测突变镜头，然后使用亮度和色度信息检测渐变镜头。
Experiments result show that it can detect shot boundary quickly and exactly from compressed video.
实验表明，该方法能快速、准确地检测出视频中镜头的边缘。
The basic idea is to detect the shot boundaries first for news video, and then frames containing topic caption texts are identified to get news story segmentation cues using text detection algorithm.
其基本思想是先对新闻视频进行镜头边界检测；其次，通过文字检测算法检测包含有主题字幕文本的帧来获得新闻故事分段的线索；
