| 摘 要： | 用于版权认证的数字水印技术应满足安全性.鲁棒性和不可见性.为满足此三方面的要求,提出了一种基于视觉显著性和置乱技术的小波域鲁棒性水印算法.算法利用Arnold变换实现水印图像的置乱处理,通过小波空频分解,根据计算载体小波系数显著性指标确定水印的嵌入强度,最后进行小波系数融合嵌入.实验结果表明,文中算法能够抵抗常见攻击手段,具有较高的安全性、鲁棒性和不可见性.

| Abstract: | The digital watermarking technology for copyright authentication should meet the requirements of security,robustness and invisibility.Thus,a robust digital watermarking algorithm in wavelet domain using Visual Saliency and Scrambling Technique is proposed.The algorithm,using arnold transform,implements the scramble processing of the watermark image.After space frequency wavelet decomposition,according to the saliency of wavelet coefficients of the carrier,the embedded watermark strength is determined.Finall... |
