摘要
建立了字符平滑的元胞自动机模型,用于处理字符图像中常见的黑白噪声,通过分析元胞自动机的局部转换函数,编写了相应的演化规则和算法,最后利用MATLAB编程分别对不同的含黑白噪声图像进行了处理,平滑效果良好,并与传统中值滤波方法进行比较,说明将元胞自动机用于字符图像平滑是一种非常有效的方法,同时元胞自动机适合并行计算,该方法也为图像处理的VLSI电路实现提供了一种新的途径.
The model of character image smoothing based on cellular automata(CA) was established for black and white noise.By analyzing the local transform function,we compiled evolvement rule and algorithm.The different character images containing black and white noise were processed by using MATLAB.Comparing with the traditional median smoothing,the algorithm is more effective by applying CA to character image smoothing.Meanwhile,it is a new way to design VLSI circuit for image processing.
