摘要
根据高阶平衡的插值多小波具有的优良性质,提出了一种双彩色图像水印新算法.该算法只须对彩色的宿主图像、水印和含水印图像的R,G,B各分量分别进行多小波变换或逆变换就可实现,具有较高的执行效率,且实验证明该水印系统具有良好的透明性和鲁棒性.
Based on the fine properties of cardinal multi - wavelet with high - order balance, a watermarking algorithm of dual color images is proposed in this paper. The realization of this scheme only requires taking the discrete multi -wavelet transform （DMWT） or inverse DMWT （IDMWT） to the R, G, B elements of the color host image, watermark image and watermarked image respectively, so the technique greatly improves the watermarking efficiency. Moreover, the experimental results show that the watermarking system has good transparency and robustness.
