The simulation results show the proposed method can effectively filter the impulse noise and deduce the negative impact on image smoothing by the median filter.
并通过仿真说明该算法能够比较好的滤除冲激噪声和减小中值滤波对图像引入的平滑效应；
2
The second subunit is median filter, which use the median of non-noise pixel in the window to replace the detected noise pixels.
第二部分是中值滤波器，对于检测出的噪声像素，用其相应窗口内的非噪声像素的中值进行替代。
3
The simulation results reached nearly ideal filter characteristics, and the performance of removing image noise using this filter was compared with the median filter.
