摘要 利用从DCT域直接提取的图像主色信息构造MPEG-7所建议的一种颜色布局描述符,提出一种考虑图像主色分布和尺寸的压缩域图像检索方法,应用于基于内容的图像检索. A image retrieval method in discrete cosine transform（DCT）compressed domain,which considers the location of all main color component and image size,is presented through constructing the color layout descriptors proposed in MPEG-7 by extracting the main color information from DCT domain directly.The proposed method may be applied to content-based image retrieval.
