摘要
图像数据的无序激增使得基于内容的图像检索技术成为一个研究热点。为了克服普通颜色特征不考虑颜色空间分布的缺点,提出了一种基于小波变换的图像多分辨率分块特征点提取方法,采用多分辨率的分块策略对图像的二维空间进行划分,多分辨率的分块策略使得相关反馈的自适应性得到了更好的保证,实验证明文中所给的方法是十分有效的。
Content-based image retrieval becomes a hot research topic due to the rapid increase of out of order image data. In order to solve the problem of lacking the spatial knowledge of common color features, presented an approach based on feature points for the content-based image retrieval. Meanwhile, the technology of relevance feedback was combined with the algorithm presented in the paper to enhance the effectiveness of retrieval. The comparison of the retrieval results to that of other systems shows that the approach proposed in the paper is effective.
