Description: 高斯平滑是去除图像噪声的一种方法,用低频滤波器处理,低通滤波器的作用就是滤掉高频分量,从而达到减少图象噪声的目的,高斯平滑指的是滤波用的模版是高斯(guass)模版,通过采样2维高斯函数得到。-Gaussian smoothing is to remove the image noise is a means to deal with low-frequency filter, low pass filter function is to filter out high frequency components, so as to achieve the purpose of reducing the image noise, Gaussian smoothing refers to the filter used template is a Gaussian (guass) template by sampling 2-dimensional Gaussian function to be.
