| 摘 要： | 镜头检测是基于内容的视频检索的重要基础。视频文档具有数据量巨大，抽象程度低等特点，对其进行有效的存储、检索成为需要解决的迫切问题。根据MPEG编码的特点，提出了一种基于Rough Set的镜头检测方法。该方法能有效地区分镜头运动与渐变。实验表明，利用本文方法进行镜头检测能取得较好的效果。

| Abstract: | Shot detection is the basis of content-based video retrieval. Video files have the characters of huge data volumes and low level of abstraction, and effective storage and retrieval the video files becomes issues that need to be solved urgently. According to coding characteristics of MPEG, a rough-set-based video shot detection method is proposed. It can distinguish shot motion and gradual shot boundaries accurately. Experiments show that this method can provide satisfactory shot detection effects. |

| Keywords: | rough set shot detection abrupt change gradual change content-based video retrieval |
