摘要
数字图书馆中海量多媒体信息无序激增使基于内容的图像检索技术成为一个研究热点。为了克服只考虑普通颜色特征不考虑颜色的空间分布这一缺点,采用一种多分辨率分块主色法的空间颜色索引技术,并将相关反馈技术融合到多分辨率分块主色算法中,可有效地改善基于颜色特征的查询效果。文章还指出了目前研究中存在的主要问题和今后的研究方向。
With the sharp increasing of mass unordered multimedia information in digital libraries, cont-ent-based image retrieval technique has become a research focus whose purpose is to, through the adoption of the spatial color index technology to part dominant colors according to their multi-resolution ratio, improve the consulting efficiency with the combination of relevant feedback techniques and partitoned multi-resolution ratio essential color algorithm and overcome the weakness of concentrating on common color characteristics only while neglecting their spatial distribution. Besides, this paper discusses the existing problems of the current re-search and its future research direction as well.
