一种足球视频精彩事件检测方法

限于当前的技术水平,视频检索技术难以在底层特征与高层语义之间建立通用的视频分析模型。文中结合足球视频的领域知识,着重分析了一类特殊的语义事件——精彩事件,基于统计的方法提出了动态贝叶斯网络事件检测模型,以及相应的学习和推理算法。实验结果表明,该方法可有效地提取足球视频中的精彩语义事件,具有较高的查全率和查准率,较强的鲁棒性,是一种很有前景的视频语义事件检测方法;同时证明了,通过结合某一领域知识,底层特征与高层语义之间是可以建立起某种联系的。

A Soccer Video Highlights Detection Method

Limited to the current technical level,it is difficult for sport video analysis technology to establish universal video analysis model between the bottom characteristics and the high-level semantics.Through a combination of the corresponding field of knowledge,it is likely to establish links between the bottom characteristics and the high-level semantic.Combine domain knowledge of soccer video,focusing on an analysis of a special kind of semantic events,i.e.highlights.Based on statistical methods proposed d...
