舞蹈视频标注的语义建模与检索

Semantic Modeling and Retrieval of Dance Video Annotations

Rajkumar Kannan, Balakrishnan Ramadoss

摘要:

舞蹈视频是叙事视频的重要类型之一,具有丰富的语义内容。本文提出了一种新的Meta模型--舞蹈视频内容模型(Dance Video Content Model,DVCM),用于在多个粒度级别上表示舞蹈视频的表达语义。DVCM是基于MPEG-7 MDS的视频、镜头、片段、事件和对象等概念设计的。本文引入了一种新的关系类型--时态语义关系来推断舞蹈视频对象之间的语义关系。创建基于倒排文件的索引,以减少舞蹈查询的搜索时间。描述了使用精确度和召回率的包含查询的有效性。关键词:舞蹈视频注释,有效性分析,元建模,时间语义关系。

英文摘要:

Dance video is one of the important types of narrative videos with semantic rich content. This paper proposes a new meta model, Dance Video Content Model (DVCM) to represent the expressive semantics of the dance videos at multiple granularity levels. The DVCM is designed based on the concepts such as video, shot, segment, event and object, which are the components of MPEG-7 MDS. This paper introduces a new relationship type called Temporal Semantic Relationship to infer the semantic relationships between the dance video objects. Inverted file based index is created to reduce the search time of the dance queries. The effectiveness of containment queries using precision and recall is depicted. Keywords: Dance Video Annotations, Effectiveness Metrics, Metamodeling, Temporal Semantic Relationships.
