不变小波域内基于DWT的图像数字水印

An image digital watermarking based on DWT in invariant wavelet domain

  • 摘要: 面对各种几何攻击,现有数字水印算法露出各种缺陷,到目前为止还没有发现真正能抵抗各种攻击特别是几何攻击的算法.利用具有旋转、伸缩、平移不变性的RST不变小波变换设计了一种新颖的基于量化边通信模型的DWT盲数字水印算法.实验表明,这种新颖算法对于旋转、伸缩、平移等普通几何攻击以及滤波与噪声等多种攻击具有较好的鲁棒性,但该算法对局部几何攻击具有一定的敏感性.

     

    Abstract: In the face of geometrical attacks,all shortcomings of the almost all digital watermarking algorithms have been exposed.Perhaps there is no algorithm against every attack especially geometrical attacks.It is designed a novel blind image watermarking algorithm of Scalar Costa System based on the DWT transformation in the Rotation-and Scale-and Translation-(RST) Moment Invariant Wavelet,i.e.RSTMIW domain.The experiments show that this novel algorithm is robust against RST geometrical,filter and noise attacks,however,sensitive to some local geometrical attacks.
