摘要
作为最新一代的多媒体内容描述接口标准,MPEG-7正在走向成熟和实用。现提出一种基于MPEG-7标准的混合交通视频流模型,称之为基于检测的交通视频描述模型,称之为DDTV(detection-based description model for mixed traffic vide-o)。MPEG-7标准是一种用来描述所有多媒体数据的接口框架,因此它的结构极其复杂。为了描述的可操作性、规范性和易用性,在MPEG-7描述的基础上构建了基于语义的视频描述模型:基于检测的交通视频描述模型:DDTV。该模型可以满足信息系统中对混合交通视频描述的需求,大大简化了用户对视频的描述工作。
As the latest generation of description interface standard, MPEG-7 is getting more and more mature and practical. In this paper, a mixed traffic video flow model based on MPEG-7 is proposed, which we call the DDTV （detection-based description model for mixed traffic video）. MPEG-7 standard is used to describe all of the multimedia data of the interface framework, therefore, its structure is very complicated. For the operational, regulatory and facilitating of the description, we construct the video description model based on the semantics that is on the basis of the description of MPEG-7. DDTV can meet the need of the mix traffic video description in information systems, which can greatly simplify the video description work for the users.
