SFLA

这个函数提供灰度拉伸功能，输入图像应当是灰度图像，但如果提供的不是灰度图像的话，函数会自动将图像转化为灰度形式。x1，x2，y1，y2应当使用双精度类型存储，图像矩阵可以使用任何MATLAB支持的类型存储。(This function provides a gray scale stretching function of the input image should be grayscale image, but if not provided, then gray image, the function will automatically be converted to grayscale image form. x1, x2, y1, y2 should use double precision storage, image matrix can store any type of MATLAB support.)

this source code is useful to do cdma simulation in awgn channel..

to find the iris radius and center using image thresholding and center approximation..

说明：  实现理想维纳滤波和FIR滤波对比。其中信号s(n)=as(n-1)+w(n),a=0.95(Achieve the desired Wiener filter and FIR filter comparison. Where the signal s (n) = as (n-1)+ w (n), a = 0.95)
