提出了一种基于多维时间序列分析的视频摘要关键帧选择方法。在所提出的方案中,给定的视频首先被分割成一组顺序剪辑包含一些相似的帧。然后通过聚类过程选择关键帧作为每个结果视频剪辑中最接近聚类中心的帧。该算法在广泛的测试数据上进行了实验,并与文献中的最新方法进行了比较,结果表明该算法在基于一致性的度量和主观感知方面表现出优异的性能,优于现有的帧选择方法。
This paper presents a novel method of key-frame selection for video summarization based on multidimensional time series analysis. In the proposed scheme, the given video is first segmented into a set of sequential clips containing a number of similar frames. Then the key frames are selected by a clustering procedure as the frames closest to the cluster centres in each resulting video clip. The proposed algorithm is implemented experimentally on a wide range of testing data, and compared withstate-of-the-artapproaches in the literature, which demonstrates excellent performance and outperforms existing methods on frame selection in terms of fidelity-based metric and subjective perception.
