摘要 在研究了小波变换的理论知识以及小波变换在图像处理中的应用的基础上,实现了一种基于小波变换的图像水印算法,同时在图像的小波变换域实现了水印的嵌入和提取。仿真实验结果表明本文的水印算法具有较好的不可见性及较好的鲁棒性,水印能够抵抗加噪、压缩、滤波等常用的信号处理操作。 A kind of watermark algorithm based on the wavelet transformation is presented which is in the basis of studying the wavelet transformation theoretical knowledge as well as the wavelet transformation in the imagery processing applications, simultaneously watermark embedding and the extracting in the wavelet transformation domain of image have been realized. The simulation experiment results indicate that the watermark algorithm has good invisibility and good robustness that watermark can resist some commonly operations used in signal processing like noise attack, the compression, the filtration and so on.
