| 摘要: |
| 提出了一个足球视频中的语义镜头表示及事件查询框架。在这个框架中，定义了不同的语义镜头，并且每类语义镜头都可以由五个特征属性所刻画。在语义镜头定义的基础上，为了弥补传统的事件查询方式的不足，提出了一种用户定义事件的查询方式，它是一种基于语义镜头合成Petri网表示模型的查询方式，可以由用户自由定义所感兴趣的事件Petri网表示结构，实验证明该查询方式能有效提高查询效率，并有很大的灵活性，能适应不同广播公司的转播规则，但该查询方式需要用户具有一定的专业和领域知识。实验数据来源于2006年德国世界杯、英格兰足球超级联赛和西班牙足球甲级联赛。 |

| Abstract: |
| In this paper, a semantic shot representation and event query framework for soccer video is proposed. In this framework, various semantic shots are defined and each shot can be described by five properties. In order to solve the problem in traditional event query, a user-defined event query method is also proposed, which utilizes the Semantic Shot Composite Petri-Nets. Based on the representation of the semantic shot, users can define their favorite events by Petri-Nets. The experiment conducted shows that the query method can greatly improve the query efficiency and adjust self-adaptive as the broadcaster varies, but this method requires users to have enough professional knowledge. Experiment data set includes Germany World Cup 2006, English Premier League and Spanish First Division. |
