摘要
随着互联网上多媒体资源的急剧增加以及移动设备功能的不断完善,如何在海量多媒体资源中快速检索出所需要的资料显得至关重要。传统的基于关键词描述的多媒体检索技术因其描述能力有限等原因已不能满足用户对于多媒体语义内容的检索要求,而且这些技术直接应用到性能相当有限的移动设备上也是不可行的。移动设备用户对精确而快速地检索多媒体资源的需求越来越强烈。本文详细介绍了在移动设备上进行基于内容的多媒体检索技术的研究成果。相比现有技术,这些研究成果无论准确度还是速度都有很大提升。
With the dramatic increase of the online multimedia resources and the ongoing advance in the functionality of mobile devices, how to search the needed information from so many multimedia resources has been becoming mbre and more important. Due to their well known limited description ability etc, the traditional keywordbased retrieval approaches can no longer meet the retrieval demand of users. Furthermore, applying these kinds of multimedia retrieval techniques to mobile devices directly is not feasible. Meanwhile, mobile device users have a growing eagerness to retrieve muhimedia resources quickly and precisely. This paper describes the achievements of the research in muhimedia retrieval techniques, which are based on the content and aim to be run on mobile devices, in detail. These new techniques function more precisely and rapidly, compared with existing techniques.
