We give a new digital watermarking scheme in wavelet transform domain. This scheme utilizes excellent properties of wavelet transform and some characteristics of human visual system (HVS). Based on the visibility model in wavelet transform domain, watermark is added in subband images with different directions and levels so that the amplitude of watermark added in each coefficient does not exceed the distortion marked by it. Hence, our scheme improves the robust of watermarking at the most invisibility...

给出了一种在小波变换域中给图像加水印的方案.本方案利用了小波分析的优良性质,结合人类视觉系统(HVS)的特性.基于小波变换域中的视觉门限模型,对小波变换后的图像系数按不同的方向、层次子带分别加水印,使得在每个小波系数所加的水印的幅值不超过此系数所能掩盖的失真,这样可以保证水印在不可视的前提下尽可能提高坚固性.模拟实验结果表明这个方案取得了良好的效果.

As an effect method to provide copyright protection for digital media,digital watermarking has drawn extensive attention recently.This paper proposes an adaptive image watermarking based on block classification.The algorithm splits the original image into blocks and classifies these blocks based on visual masking.Watermark components with different strength are inserted into some DCT coefficients according to the classification.The experimental results demonstrate that the watermarks generated with the proposed algorithm are invisible and robust against noise and commonly used image processing techniques.

数字水印作为数字媒体版权保护的有效办法,近年来在国际上引起了人们极大的兴趣与注意.提出了一个利用块分类的自适应图象水印算法.为了实现自适应,将原始图象分块并设计了一个基于视觉掩蔽特性的分类器.根据分类的结果,不同强度的水印分量被嵌入到不同图象块的DCT低频系数中.实验结果表明,应用所提出的算法实现的水印对常见图象处理和噪声干扰具有很好的稳健性.

Digital watermarking has been proposed as viable solution to the need of copyright protection and other application such as information hiding,since it makes possible to identify the author,owner,distributor or authorized consumer of a document.A new technique to embed the mark signal into the image is introduced.The method operates in the frequency domain to modify the DCT coefficients of an image and then uses the characteristic of Human Visual System (HVS) to enhance the robustness of the watermark...

Digital watermarking has been proposed as viable solution to the need of copyright protection and other application such as information hiding,since it makes possible to identify the author,owner,distributor or authorized consumer of a document.A new technique to embed the mark signal into the image is introduced.The method operates in the frequency domain to modify the DCT coefficients of an image and then uses the characteristic of Human Visual System (HVS) to enhance the robustness of the watermark and avoid the perceptibility of human eyes.Experimental results demonstrate that the watermark is robust to most of the signal processing techniques and geometric distortions.
