摘要:

自动生成体育视频的摘要提出了检测比赛的有趣时刻或精彩部分的挑战。传统的体育视频摘要方法利用广播体育视频的编辑约定,便于提取高级语义。然而,用户生成的视频没有被编辑,因此传统方法不适合于生成摘要。为了解决这个问题,本工作提出了一种新的视频摘要方法,使用球员的行动作为线索,以确定原始视频的亮点。基于深度神经网络的方法用于提取两种类型的动作相关特征,并将视频片段分类为感兴趣或不感兴趣的部分。所提出的方法可以应用于任何运动,其中游戏包括一系列的行动。特别是,这项工作认为剑道(日本击剑)的情况下,作为一个例子的运动,以评估所提出的方法。该方法使用具有指示视频亮点的地面实况标签的剑道视频进行训练。这些标签由具有不同剑道经验的注释者提供,以展示所提出的方法如何适应不同的需求。通过几种不同特征的组合对该方法的性能进行了比较,结果表明,该方法优于以往的摘要方法。

英文摘要:

Automatically generating a summary of sports video poses the challenge of detecting interesting moments, or highlights, of a game. Traditional sports video summarization methods leverage editing conventions of broadcast sports video that facilitate the extraction of high-level semantics. However, user-generated videos are not edited, and thus traditional methods are not suitable to generate a summary. In order to solve this problem, this work proposes a novel video summarization method that uses players' actions as a cue to determine the highlights of the original video. A deep neural network-based approach is used to extract two types of action-related features and to classify video segments into interesting or uninteresting parts. The proposed method can be applied to any sports in which games consist of a succession of actions. Especially, this work considers the case of Kendo (Japanese fencing) as an example of a sport to evaluate the proposed method. The method is trained using Kendo videos with ground truth labels that indicate the video highlights. The labels are provided by annotators possessing different experience with respect to Kendo to demonstrate how the proposed method adapts to different needs. The performance of the proposed method is compared with several combinations of different features, and the results show that it outperforms previous summarization methods.
