| 摘 要： | 中值滤波是一种非线性滤波方法。为了在尽可能消除或衰减噪声的同时很好地保留图像细节，提出一种对信号与噪声分别处理的中值滤波法，并在图像处理中应用。与常用的中值滤波法相比，采用该方法处理的图像其信噪比可以显著提高。

| Abstract: | Median filtering is a nonlinear filtering method. In order to remain the efficient signals as much as possible when the noises are removed, a effective method is proposed. A noise pixel and a signal pixel are dealt with respectively in this method and this is used in image processing. Compared with common median filtering, SNR of the image filtered with this method apparently is improved. |
