摘要

当前的视频数据库系统能够处理时态媒体(如视频和音频)的语法方面。然而,这些系统很少能够根据视频信息的语义内容来处理视频信息。此外,由于视频具有时间、空间和海量的特点,对视频数据进行手动描述既繁琐又不实用,同时内容描述往往依赖于用户的解读。我们的视频描述模型是基于面向对象编程领域提出的“基于原型的面向对象模型”。原型是具有预定义结构、内容和行为的预制对象,可以从其他原型构建新对象。通过使用原型,用户可以很容易地描述视频故事,实现和修改通常在几个故事中出现的典型场景的原型。该方法采用两种层次结构,一种基于原型的继承结构,另一种基于原型的内部结构。从这个角度来看,我们的系统包括一个分层原型菜单,它引导用户到达容易要求的原型;因此,不管用户的解释如何,故事都是一样的。

Video description model based on prototype-instance model
Current video database systems are able to manipulate syntactic aspects of temporal media like video and audio. However, few of these systems are able to manipulate video information according to its semantic content. Furthermore, manually describing video content is tedious and not practical for the video data due to the temporal, spatial, and massive characteristic of the video, meanwhile content description always depends on user interpretation. Our video description model is based on "object-oriented model based on prototypes" which is proposed in the object-oriented programming field. A prototype is a prefabricated object with a predefined structure, content and behavior from which new objects can be constructed from other prototypes. By using prototypes, the user is able to describe video stories easily implementing and modifying prototypes of typical scenes that usually appear in several stories. Our method uses two hierarchical structures, one based on prototypes' inheritance structure and another based on prototype internal structure. From this point of view, our system includes a hierarchical prototype menu, which guides the user to reach easily requested prototypes; hence, the story remains the same regardless of different user interpretation.
