| 摘 要： | 本文采用了一种基于离散小波（DWT）多分辨率分解的数字水印技术,研究了水印算法,将图像进行三级小波分解,产生三个高频带系列子图和一个低频带子图。由于人眼对高频信息的敏感度低于对低频信息的敏感度,因此,采用了把水印嵌入到小波图像的中高频系数C中。通过实例证明了如何把MATLAB应用于数字水印技术,再对含水印图像加椒盐噪声...

| Abstract: | Based on a kind of digital watermarking technique of multi-resolution decomposition,a new watermarking algorithm is proposed.3-level wavelet decomposition is applied to the image to generate three high frequency band graphs and a series of low frequency band graphs.Because the sensitivity of human vision to the high frequency information is below the sensitivity of human vision to the low frequency information.Therefore,the watermark is embedded to middle-high frequency coefficient C of the wavelet images.S... |
