本实验要求要求实现高斯低通滤波器的程序，并设定截至频率半径为15时得到如课本上图4.18图c的图。使低频通过而使高频衰减的滤波器成为低通滤波器，被低通滤波的图像比原始图像少一些尖锐的细节部分。本实验就是设计实现高斯低通滤波器。-Requirements of this experiment requires low-pass Gaussian filter procedure and set the frequency up to a radius of 15 textbooks, such a

此程序能实现很好的低通滤波，能很好的滤除低频分量，对于初学图像处理的人很有用-This process can achieve a good low-pass filtering, the filter can be a very good low-frequency components, for beginners who are useful image processing
