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.

Description: 针对 Anrlod 变换的周期依赖于图像的阶数这一特性, 提出了一种反变换算法 。 该算法 通过分析加密图像任一点处两坐标分量间关系, 得到原图像相应点的坐标 , 从而实现图像的解密。(In view of the characteristic that the Anrlod transform cycle depends on the order of the image, an inverse transformation algorithm is proposed. The algorithm obtains the coordinates of the corresponding points of the original image by analyzing the relationship between the two coordinate components at any point of the encrypted image, so as to achieve the decryption of the image.)
