- (1)为了提高水印的安全性,在嵌入水印之前首先对水印信息利用Arnold变换进行置乱。 (2)为了提高传统相关性检测方法的准确率,嵌入水印时采用嵌入两个不相关伪随机序列的方法,大大提高了检测的准确率。 (3)低频部分集中图像的大部分能量,修改这里容易引起失真,所以本文采用修改中高频部分的方法进行嵌入。 (4)本文水印的检测方法为半盲检测,只需要原始水印的部分信息的参与,所以具有重要的现实意义。 -err

- 根据Arnold置乱变换算法的过程和8位图像像素值的取值范围(0≤f(x, y)≤255),导出了一种逆变换算法。该算法假设了两个变量p和q,由Arnold正变换算法导出了四个方程组,然后再根据像素值的取值范围,计算出p和q的可能取值,针对p和q的取值组合,计算出各方程组的解,那么在所有方程组解中满足像素值取值范围的即为逆置乱的解。经分析,逆变换算法的解忧且仅有一个。-According to Arnold scrambling alg
