Evolved Cellular Automata for Edge Detection in Grayscale Images

One important image processing task is the edge detection in intensity images. Some approaches were proposed based on computing the gradient of the signal, but not many approaches were proposed based on Cellular Automata (CA). In this paper, an edge detection method based on CA evolved by the means of a Genetic Algorithm (GA) for grayscale images is presented. Promising results are obtained when compared with similar approaches in the specialized literature.
