摘要
提出了一种新的基于混沌理论的彩色图像水印方法.在空域中RGB色彩空间的蓝色信道里嵌入水印以提高水印隐性和鲁棒性.水印的检测同样只在蓝色信道里进行,通过相关性的比较来确定结果.实验结果表明,文中所提出的水印方法速度快、易于实现,具有较高的安全性,并对包括剪裁在内的几何攻击有很好的鲁棒性.
This paper proposes a new theory of chaos-based Color Image Watermarking Method. The watermark is embedded in the spatial domain into the blue channel of RGB color space in order to increase invisibility of the watermarks. Watermark detection is performed in the blue channel too, and determine the results by computing the statistical correlation. Finally experimental results show that the proposed watermarking method is quick, easy implementation of high security, and has good robustness, in geometric attacks including clipping.
