视频摘要作为一种视频内容的简要表示，能够有效地增强用户浏览和组织视频的效率。提出了一种基于草图的视频摘要生成方法。与以往的静态视频摘要方法不同，该方法结合视频内容分析，利用草图在表达上的简洁性和抽象性，对视频中的主要内容进行表达。首先通过视频分析获取视频中的语义特征并提取关键帧，然后通过交互式的方法从关键帧中生成草图，最后进行摘要布局生成完整的视频摘要。实验结果表明，该方法能够有效突出视频的主要对象和主要事件，并具有较高的用户满意度。

As a brief representation of video content, video summarization can effectively assist users’ browsing and organizing video clips. This paper presents a novel method to generate video summarization based on sketches. Based on the result of video content analysis, this method visualizes video’s main content, taking advantages of sketches’ efficiency and succinctness. Firstly, we extract semantic features and key frames from the video. Secondly, user interaction is adopted to generate sketches from the key frames. Finally, the layout is arranged to get the final summarization result. Experiment result shows that the method can represent the main objects and main events of video materials, and has a quite high user satisfaction.
