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。
The proliferation of massive multimedia information in digital libraries has made content-based image retrieval technology a hot research topic. In order to overcome the shortcomings of considering only the common color features without regard to the spatial distribution of colors, a spatial color index technique based on multi-resolution block primary color is adopted, and the relevant feedback technique is integrated into the multi-resolution block primary color algorithm , Which can effectively improve the query results based on color features. The article also points out the main problems in the current research and future research directions.
