中文说明：
用fibonacci变换方法对图象做置乱或逆置乱，效率极高，在信息隐藏中属常用的方法之一。调用函数为f=fibonacci_t(I,r,s)，其中参数分别为I=被置乱的图像，r=置乱密钥，s=0置乱，s=1逆置乱。
English Description：
Using Fibonacci transform to scramble or reverse scramble the image is very efficient. It is one of the common methods in information hiding. The calling function is f = Fibonacci_ T (I, R, s), where I = scrambled image, r = scrambling key, s = 0 scrambling, s = 1 inverse scrambling.
