对一副M*N大小的图像重复使用截频为D0的高斯低通滤波器进行滤波。假设K为滤波次数。并从理论上说明当K足够大时的滤波结果及产生原因(Right an M* N size of the image is repeated using the cutoff frequency for the D0 of a Gaussian low-pass filter for filtering. Assuming K is filtering times. And filtering results when K is large enough and theoretically causes)

关于滤波的程序，可以减少Gipps效应，提高信号的分辨率。(On filtering procedures, can reduce the Gipps effect, improve the resolution of the signal.)
