Through summarizing the characteristics of pulse noise and analysis of PCNN's work principle,a novel method of color image filtering of Gause noise is presented,which based on PCNN with characteristics of human visual color consciousness in RGB color pattern.Firstly,the noisy points are located using the syn-chronous pulse burst property of PCNN,then,are locally processed using the median filter.Finally the algorithm is compared with median filtering,other filtering.Experimental results show that the median filtering algorithm based on PCNN and RGB not only can effectively remove the noise,but also can protect the details of color image better.
