| 摘 要： | 关键帧提取技术是基于内容检索和视频分析的基础。关键帧的使用减少了视频索引的数据量,同时也为视频摘要和检索提供了一个组织框架。首先介绍了目前关键帧提取技术,然后提出了一种基于互信息量的关键帧提取方法,该算法以帧间互信息量来衡量两帧图像内容的相似性,可以对具体镜头按其特点自动提取出一个或多个关键帧。实验结果表明这种方法可以较好地概括视频内容。

| Abstract: | Key frame extraction is a fundamental process for content-base video retrieval and video analysis.Key frame can dramatically reduce the data of the video indexing,and provide a framework for video abstraction and retrieval.At first briefly the existing approaches is discussed,and then a method of key frame extraction based on mutual information is presented.The algorithm is to measure the similarity of the content of the image of 2 frames based on the amount of mutual information between frames,which can ex... |
