摘要:
提出了一种基于离散小波变换(DWT)和奇异值分解(SVD)的双重水印算法,其所嵌入的水印是由两幅不同的水印图像组成,将其中的一幅水印图像嵌入到另一幅水印中得到双重水印图像,对双重水印图像进行Arnold变换,然后再将其嵌入到宿主图像中.当数字产品遭到恶意破解后,水印中仍然有一层水印信息,可以更好地维护版权信息.实验结果证明了该方法对于JPEG压缩、噪声、旋转、剪切等具有很好的鲁棒性.
Abstract:
An a lgor ithm o f double-leve lw aterm a rking based on DWT and SVD is proposed in th is pape r. The embedded w aterm arking im age constits of tw o d ifferen t im ages. Firstly, one im ag e is em bedded into ano ther, then Arno ld transform is perform ed on the m ixed im age, w hich is late r embedded into the host im ag e. If them ixed w aterm arking inform a tion is go t v ic iously, a level o f deep-seated wa term ark ing still rema ins to pro tect the copy right better. Exper im enta l resu lts a level of dem onstrate tha t the proposed approach is robust aga inst comm on signal processing such as JPEG com pression, no ise, rota tion and c ropp ing.
