Adaptive_blind_watermark_algorithm
- 一种嵌入可读水印的自适应盲水印算法， 本文提出了一种基于DWT的嵌入可读水印的自适应盲水印算法,通过分析图像经离散小波变换后细 节子带系数的特性,把细节子带系数的均值和方差作为水印信息的一部分来自适应地修改图像小波分解后某些细节 子带的系数值,在满足水印不可感知性的条件下自适应地嵌入水印信息,实现了水印不可感知性和鲁棒性之间的折 衷. 同时,水印的提取无须求助于原图像,很好的实现了水印的盲检测. 这里的水印是一幅有实际意义的二值图像. 实 验结果和攻击测试表明,本文提出的算

基于 QR 码的自适应抗打印扫描水印算法
- 提出一种基于 QR 码的自适应抗打印扫描盲水印算法。方法 首先对载体 QR 码进行三级小 波变换，并对低频部分进行 4×4 分块 Schur 分解，然后利用子块酉矩阵的系数差值的稳定性，将二值 水印信息自适应嵌入到载体 QR 码中，最后对含水印 QR 码打印扫描并提取出水印信息。同时，算法实 现了盲提取。结果 算法能较好抵抗打印扫描攻击，并对高斯噪声、椒盐噪声、斑纹噪声、泊松噪声、 JPEG 压缩等攻击具有较强的鲁棒性。结论 算法具有较强的抗打印扫描性能，可以广泛应用于数字产品 的版权保
