摘要: 提出了一种新的基于小波变换的彩色图像双水印算法,首先把RGB彩色图像转换为YIQ空间模型图像,并对提取的亮度分量Y进行离散小波变换;利用Arnold变换和纠错编码分别对两类水印进行了预处理,而后将它们作为水印以不同的方式嵌入到小波变换系数中,且实现了水印的盲提取。理论分析和实验仿真表明该算法对常见的水印攻击表现出了较强的鲁棒性。

Abstract: A novel dual-watermarking algorithm based on wavelet transform for color images is proposed.Firstly,the RGB color image is transformed into YIQ color space,and then the Y is decomposed with discrete wavelet transform.Arnold transform and error correcting coding are adopted in the watermarking processing,and then they are embedded into the detail sub_image.Mostly,this algorithm can also realize blind extraction.The watermark generated with proposed algorithm is imperceptible and of better robustness against common attacking processing methods.
