edge-detecting-based-susan

用matlab编程绘制矩形窗函数的幅频特性，窗函数形状的长度为10，20，50，100.(Programming using matlab draw rectangle window function of the amplitude-frequency characteristics, the shape of window function of length of 10,20,50,100.)

低通滤波，属于频域滤波，先做傅里叶变换，再把中心移到原点，距离中心远的代表噪声信息，舍去(low-pass filter in Fourier domain)

使用MATLAB实现运动目标检测，用的是背景差分法(moving detection by matlab)
