摘　　要：提出了一种新的基于元胞自动机变换的图像边缘检测方法。应用二维元胞自动机,首先确定合适的二维变换基函数,然后对图像进行元胞自动机变换,将变换系数进行子带编码,再根据基函数的性质,分离出变换系数中的高频部分,最后经过反变换得到图像的边缘信息。此算法简单实用,仿真实验结果较好。A new edge detection method based on cellular automata transforms is presented in this paper. An appropriate two-dimensional transform base ftmction is first calculated, and then the cellular automata transforms are performed on an image and the transformation coefficients are sub-band encoded. The high frequency components of the transform coefficients are separated according to the property of the base function and reverse transformed to provide pertinent information on the edges of the image finally. The algorithm is simple and practical and better effect is testified by the result of emulator.
