摘    要:本文提出一种新的图像检索系统,采用数据隐藏算法把图像的标注信息和特征信息嵌入压缩域图像中,用于快速检索。由于DCT在图像压缩中得到了广泛的应用,本文分析了基于DCT的JPEG图像格式编码流程,实现了一种基于JPEG压缩的数据隐藏算法。实验结果表明,该算法未引起图像质量明显下降,可嵌入较多数据。

关 键 词:数据隐藏  图像检索  JPEG图像编码

Abstract:In this paper a new image retrieval system is proposed, embed text information and image attributes inside the compressed images for their quickly retrieval. Because the DCT got the extensive application in picture, compress, this paper analyzes the JPEG picture format process based on DCT,carry out a kind of data hiding method according to the JPEG image compression. Experimental results show that this method did not cause the picture quantity to descend obviously,can embed the more data.
Keywords:Data hiding Image retrieval JPEG image compression
