摘要: 提出了一种新的、对打印和扫描( 几何失真和噪声较小) 具有鲁棒性的图像水印算法.该数字水印是一种嵌入在傅里叶域并且被调制在高的载波频率的类方形噪声.文中还基于盲检测检验了几种不同的嵌入方法在不同失真上的鲁棒性,在载波频率实现了水印和傅里叶系数的归一化2D 相关检验.

Abstract:

In this paper,a new image watermarking algorithm is introduced,which is designed to be robust against print and scan (i.e.slight geometrical distortions and noise).The digital watermark is a square noise-like pattern that is embedded in the Fourier domain and is modulated at a high carrier frequency.Then,several embedding methods are evaluated with respect to their robustness against various distortions.The detection is blind; normalized 2D correlation between the watermark and the Fourier coefficients at the carrier frequency is performed.
