运动模糊图像的复原中经常要用到点扩散函数psf,该程序实现求取点扩散函数psf，即实现Matlab中的fspecial函数（求psf），你只要设定好参数length和angle就可以了，调用get_psf()- Motion-blurred images are often used to recover the point spread function psf, the realization of the program to strike a point spread function psf, namely fspecial function in Matlab (for psf), you need to do is set the parameters of length and angle you can, make a call to get_psf ()
