代码说明:

主要思想是从两幅图像中选取信息,然后置乱成一幅图像。 这样可以从要加密的多幅(2*n幅)图像中,按照上述思想,得到一半数目(n幅)的图像。 对得到的图像进行自适应算法的隐藏,又可以得到(n-1)幅的图像。 对(n-1)幅的图像进行Arnold变换,得到(n-1)幅的图像作为密钥,此外,密钥还有迭代次数,置乱规则,Arnold加密规则 主要缺点是Arnold的周期较大,程序的运行的时间长些,我的电脑需要8分钟,另外,Arnold只能处理方阵 图像的置乱加密算法很多,本程序中用到的置乱加密算法只是其中一种方法,仅仅提出一个多幅图像加密的思想,后期还有许多的工作要做。

    C,C++ Questions 1. Base class has some virtual method and derived class has a method with the same name. If we initialize the base class pointer with derived object,. calling of that virtual method will result in which method being called? a. Base method b. Derived method.. Ans. b 2. For the following C program #define AREA(x)(3.14*x*x) main() {float r1=6.25,r2=2.5,a a=AREA(r1) printf(" Area of the circle is f", a) a=AREA(r2) printf(" Area of the circle is f", a) } What is the output? Ans. Area of the circle is 122.656250 Area of the circle is 19.625000 3. What do the following statements indicate.
