摘要
针对JPEG压缩图像,根据感知相似性,提出一种基于颜色聚类带相关反馈的快速压缩域索引和检索方法.该方法直接在YCbCr空间上进行,可提高图像特征提取的速度、节省存储空间.实验结果证明了本方法的有效性.
A fast compressed domain image indexing and retrieval method based on color clusters and relevance feedback was presented' which aimed at JPEG images and kept to color peceptual similarity. As the method was directly operating in the YCbCr space, the speed of extracting image features was improved improved andstorage space saved. The experimental results demonstrate the effectiveness of the proposed method.
