视频镜头边界检测的实验设计

An Experiment Design on Video Shot Boundary Detection

视频的镜头边界检测是视频处理技术的根本和关键。它有助于建立一个层次化的视频结构,从而有利于提取有意义的视频内容。在学术界得到广泛公认的是,镜头的边界检测是视频分析、处理和应用中的第一步骤。视频的镜头边界检测,长期以来吸引了众多学者的关注和研究。文中设计了一个检测视频镜头边界的实验:首先,使用MPEG视频解码器得到视频帧序列;然后,提取视频帧的RGB颜色空间特征;最后,运用阈值判别方法,来检测视频镜头边界的变换。

Video shot boundary detection is fundamental and important among video processing techniques. It helps to build a hierarchical video structure, which is conducive to extract the meaningful video contents. In the research area, it is widely recognized that shot boundary detection is the first step for video analysis, processing and applications. The detection of shot boundary has attracted much attention from researchers. In this paper, an experiment on video shot boundary detection is designed. Firstly, the video frame sequence is obtained by the MPEG decoder. Then, the features from the RGB colour space are extracted. Finally, the video shot boundary is detected by applying the threshold checking method.
