| 摘 要： | 提出一种基于色彩空间变换和离散小波变换(DWT)的彩色图像水印算法.算法首先将彩色原始图像和彩色水印图像从RGB模式转换到YIQ模式,然后将彩色水印图像的Y,I,Q分量分别嵌入到彩色原始图像Y,I,Q分量的DWT变换系数中.该算法的特点是方法简洁,嵌入水印信息量大,提取的水印可视效果良好.通过大量实验表明,该算法对常见的攻击具有较强的鲁棒性.

| Abstract: | A color image - watermarking algorithm based on color spatial conversion and DWT is proposed. In this paper, firstly, the color original image and color watermark image are converted from RGB mode to YIQ mode, then Y, I and Q of color watermark are embedded into coefficients respectively which Y, I and Q of the color original image use DWT. The characters of this algorithm are simple, much more watermark information embedded and good visual quality to detected watermark. By a lot of experiments testifying, the algorithm has strong robustness to some common attacks. |
