摘    要:基于图像高频子分量相互独立的属性,再结合图像低频能量不易丢失的特点,该文设计了多分辨率子带分解的快速独立分量分析(MSD-FICA)盲水印算法,借鉴了经典的量化调制水印(QIM)算法思想,对原始图像小波分解后的高频成分(水平、垂直、对角小波系数)进行排序,取中频成分。嵌入水印是对中频分量系数和低频分量系数同时嵌入,水印的提取采用快速独立分量分析(FICA)算法,先用主成分分析进行预处理,然后用FICA盲提取水印。实验表明,该算法能有效地提取出水印,并能抵抗一定的压缩、滤波、噪声攻击。

关 键 词:盲水印算法  数字水印  图像属性  小波

Abstract:A blind image watermarking algorithm based on the multiresolution sub-band decomposition-fast independent component analysis (MSD-FICA) is proposed. In this scheme, the watermark bits are embedded in the middle-frequency components and the low-frequency components simultaneously. The middle-frequency components are selected by adopting the sorting scheme among the high-frequency components. In watermarking extraction, primary component analysis (PCA) is applied for preprocess, then the watermark is extracte...
Keywords:blind watermarking algorithm  digital watermarking  image property  wavelets
