摘　　要：为滤除手写汉字识别图像预处理中二值图像上的噪声点,结合中值滤波和细胞自动机滤波方法,提出一种二值图像CA-M(CellularAutomata-Median)滤波方法,并给出具体的算法流程.利用该方法进行滤波去噪实验并计算算法效率,对二值图像去噪非常有效.The Cellular Automata-Median （CA-M） filter method is proposed to filter the noisy points in binary image for the image recognition pretreatment of handwritten Chinese characters and the detailed algorithm flow is presented. The experiment for the method is done to reduce noise by median filter and the algorithmic efficiency is calculated. The experimental results show that the method is highly effective for noise reduction in binary image.
