Description: (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。

Description: 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 algorithm process and 8-bit image pixel value range (0 ? f (x, y) ? 255), derived a kind of inverse transform algorithm. The algorithm is assumed that two variables p and q, by Arnold transform algorithm is derived for the four equations, and then in accordance with the range of pixel values to calculate p and q possible values for p and q values combination of the equations to calculate the solution, then all equations in the solution to meet the pixel value range of which is the solution of inverse scrambling. After analysis, inverse transform algorithm and only one of the worries.
