摘　　要：结合视觉特性和小波变换,提出了一种基于Fibonacci置乱变换的双彩色图像水印算法.该算法首先对彩色宿主图像进行三基色分离和小波变换,然后将Fibonacci置乱变换后的彩色水印图像数据嵌入到宿主图像对应基色的低频小波系数中,较好地实现了彩色水印的嵌入及提取.实验结果表明,该算法在保证透明性的同时对多种常规攻击具有较强的鲁棒性.Combined with the HVS and the DWT,a double color image watermarking algorithm based on Fibonacci scrambling transform is proposed.Firstly,the color host image separation and wavelet transform to the three primary colors are carried out.Then,the color watermark image data after Fibonacci scrambling transformation are embedded into the host image wavelet coefficients corresponding to the low-frequency color,which realizes the color watermark embedding and extraction.The experimental results show that the algorithm is robust enough to fight against various conventional attacks.
