fibonacci_t
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(Fibonacci transformation method used to do on the image or inverse Scrambling Scrambling, high efficiency in the information hidden in one of the methods are commonly used. Call the function f = fibonacci_t (I, r, s), which parameters were I = have been scrambling the image, r = scrambling key, s = 0 Scrambling, s = 1 inverse Scrambling)

MATLAB
常规的中值滤波器,在噪声的密度不是很大的情况下效果不错。但是当概率出现的概率较高时,常规的中值滤波处理后,仍然具有噪声点,并丢失了细节和边缘,效果不是很好。
自适应中值滤波器可以尽可能的保护图像中细节信息,避免图像边缘的细化或者粗化。(The conventional median filter works well when the noise density is not very large. However, when the probability of probability is high, the conventional median filter still has noise points, and the details and edges are missing. The result is not very good.
The adaptive median filter can protect details in the image as far as possible and avoid thinning or coarsening of the image edges.)
