In order to improve the performance of median filter and enhance adaptability for different intensity pepper-salt noise, a median filter based on noisedensity estimation is proposed.
为了提高中值滤波器的滤波性能和适应不同强度的椒盐噪声，提出了基于噪声强度估计的中值滤除算法。

The density of the streets, the noise and the rush of people, astonished her.
密集的街道和拥挤嘈杂的人群让她惊奇。

The median filtering is a common method in image processing, but it is limited when it faces the swash noise of space high density, because it depends on the fixed Windows and the data points.
