The intensity of pulse noisy pixels significantly differs from adjacent pixels of image. The de-noising will be accomplished by modifying the intensity of the noisy pixel according to the firing patterns of adjacent neurons of PCNN. At last, this dissertation suggests a new kind of filter for de-noising pulse noise based on the PCNN and median filter. It is very simple, and the simulation experiment of the image processing shows that the de-noising effect is much better than neighborhood averaging method and median filter.

一般脉冲噪声点与其所在图像像素灰度值之间相关性很差，而PCNN脉冲耦合神经网络能使相似神经元同步激发；这就决定亮点脉冲噪声像素对应神经元会在其区域所在相邻神经元中首先激发，为此结合中值滤波，我们提出了结合PCNN脉冲耦合神经网络和中值滤波的混合滤波新算法，理论分析和实验证明，该方案在滤除噪声的同时，比常规中值滤波更有效地保持了图像的高频细节信息。
