According to the basic principles of information theory, computer graph processing and the chromatics, this thesis mainly researches on the theory and applications of the color images watermark using the characteristics of the human visual system. And then it discusses the preprocessing method such as Image color inversing and image disordering, especially the method of watermark embedding, watermark extracting and watermark attacking etc. At last, an experimental system about watermark embedding and extracting are accomplished.

本文首先根据信息论、计算机图形处理和色彩学中的基本原理，结合人眼的视觉系统特性，对彩色图像水印的理论与应用进行了研究，然后讨论了如何对水印图像进行反色和置乱预处理，尤其是对水印嵌入过程、水印提取过程和水印攻击方法等进行了深入探讨，并最终设计实现了一套完整的具有水印嵌入与提取功能的实验软件。

The main task of this paper is a digital watermark image signal, the process is the first image signal by adding a watermark information, the next to detect digital watermark information extraction, the final image of the embedded watermark different attacks, the test of robust watermark sexual.

本次论文任务主要是对图像信号实现数字水印，过程首先是对图像信号加入水印信息，接下来对数字水印信息进行检测抽取，最后对嵌入水印的图象进行不同的攻击，测试水印的鲁棒性。

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.

为了提高水印图像的安全性，提出了一种基于TD-ERCS混沌映射的二值水印图像的加密算法，该算法利用TD-ERCS映射产生的混沌序列加密水印图像；将离散混沌映射和二维离散小波变换相结合，研究了彩色图像水印新算法，该算法先对混沌序列加密后的水印图像进行小波变换，再嵌入到宿主图像的蓝色分量的最深层的四个子带中，嵌入位置则由广义猫映射确定；将整数小波变换和图像子采样技术应用于数字水印，提出了一种彩色图像盲提取水印算法，水印嵌入时，先对宿主图像在YIQ色彩空间中的Y分量进行子采样，并对得到的四个子图像分别进行二级离散小波变换，然后将置乱并加密后的水印图像嵌入到小波变换后的低频子带中，其嵌入位置由Logistic混沌映射产生的混沌序列确定，实现了水印的盲提取。
