NR – Noise Reduce 总结(NR – noise reduce summary)

均值滤波是对窗口内的数值进行平均处理,能够很好的去除高斯噪声,但是对椒盐噪声效果差,会丢失细节。

中值滤波能很好的去除脉冲噪声,保留尖锐的边缘,对椒盐噪声表现好,但对高斯噪声表现差。

Mean filtering is to average the values in the window, which can well remove Gaussian noise, but it has poor effect on salt and pepper noise and will lose details.

The median filter can remove the sharp noise, but the median filter can remove the sharp noise very well.
