该文是中国多媒体技术研究与应用的年度文献综述之七,其是在查阅了2004年9种核心刊物的2 926篇文章的基础上,从中选取了363篇多媒体技术相关的文章进行了分类、统计,以展现出2004年中国多媒体技术发展的现状。同时,通过对比前4年的统计结果可以看到,数字水印、虚拟现实、多模态接口、多媒体信息检索、服务质量保证、计算机支持的协同工作、地理信息系统和数字地球等这些国际热门技术在国内也受到了高度的重视。该文还对5年来中国多媒体技术文献统计结果做了比较,从中可清楚地看到多媒体技术,尤其是热点技术的发展过程和发展趋势。该文不仅给从事多媒体技术研究与应用的人员提供了一个很好的文献资料的索引,也给论文作者和刊物编辑一个好的参考。

As one of a serial of reports,this paper is a survey on multimedia researches and applications in China in the year 2004.Since multimedia is a cross research area,papers about multimedia technology are distributed on various journals.We checked about(2 926) papers published on 9 Chinese journals in 2004,from which we have selected 363 papers related to multimedia technology and application.Then we analyzed them and the statistics were compared with those from 2000 to 2003.Looking into the data we can find that researchers in China are continuously paying much attention to digital watermarking,virtual reality,multimodal interface,multimedia information retrieval technology,quality of service,computer supported cooperative work,GIS and Digital Earth as these fields have shown increasing research internationally.We present here an overview on the progress in multimedia technology in China,2004.This article will make convenience for researchers to find references,and be helpful for editors to edit journals and for authors contributing papers.
