| 摘 要： | 关键帧提取技术,是基于内容的视频检索的一个重要组成部分。为了能从不同类型的视频里有效地提取关键帧,提出了基于仿射传播聚类的自适应关键帧提取算法。首先通过图像的颜色特征获取视频镜头的相似性矩阵,然后通过仿射传播聚类自适应地提取视频关键帧。该算法从视频的本身信息分布出发,自适应地搜索出视频最优关键帧,且运算速度快。实验表明,该算法能有效地提取出视频最优关键帧,且算法快速稳健。

| Abstract: | Key-frame Extraction is important to content-based video analysis.For extracting key frames efficiently from different video,this paper presented an efficient method for key-frame extraction in which affinity propagation clustering is applied to key-frame extraction.First get the shot comparability matrix by histogram differences,extract key frames adaptively through affinity propagation clustering.The algorithm which this paper proposed can get the key frames adaptively according to the content of video sh... |
