中文简介:
支持基于内容访问视频信息的最广泛方式是使用视频元数据(日期、时间、格式等)和用户生成的描述(用户标签、评级、评论等)的组合。这已经得到了广泛的应用,并且是在YouTube、开放视频和互联网档案等系统中通过视频档案进行导航的基础。但是,这也有一些限制,比如词汇问题,以及注释内容的用户之间的身份验证。我们的工作主要集中在添加基于内容的视频检索,即我们通常在文本上执行的直接检索,主要基于实际内容检索网页或博客文章。
课程简介: The most widespread way in which content-based access to video information is supported is through using a combination of video metadata (date, time, format, etc.) and user-generated description (user tags, ratings, reviews, etc.). This has had widespread usage and is the basis for navigation through video archives in systems such as YouTube, Open Video and the Internet Archive. However, there are limitations with this such as vocabulary issues, and authentication across the users who annotate content. Our work has concentrated on addresing content-based video retrieval, the kind of direct retrieval we routinely perform on text, retrieving web pages or blog posts based primarily on actual content.
