在数字图像受到噪声污染后, 需要对其进行滤波。针对不同的噪声有不同的滤波方法。中值滤波对滤

除脉冲噪声有很好的效果, 但也会损失图像的部分细节, 而自适应中值滤波能够在保持图像细节的基础上

滤除脉冲噪声。-Contaminated by noise in the digital image, it needs to be filtered. Different for different noise filtering method. Median filter to filter out the impulse noise very good results, but also the loss of image detail, and the adaptive median filter can be filtered on the basis of preserving image detail impulse noise.
