中文说明：
常规的中值滤波器，在噪声的密度不是很大的情况下效果不错。但是当概率出现的概率较高时，常规的中值滤波处理后，仍然具有噪声点，并丢失了细节和边缘，效果不是很好。 自适应中值滤波器可以尽可能的保护图像中细节信息，避免图像边缘的细化或者粗化。
English Description：
Conventional median filter, in the case of noise density is not very good. But when the probability is high, the conventional median filter still has noise points, and lost the details and edges, the effect is not very good.
