Partition method based on cellular automata model, the two-dimensional image is decomposed into 2 x 2 matrix unit structure. Put forward several kinds of logical operation type, used to classify composed of black and white binary point 2 x 2 matrix graph. Based on the neural network (CNN) multi-layer structure, analyze the logic in the pyramid structure similar under the combination of graphics of binary edge detection and pooling function. Through the sync pulse form to gray image, decomposed into multiple time dimension binary graphics, convenient multi-level pyramid logic processing. Analyzed how to use time delay relay make pyramid structure logic has the characteristics of the memory. (radius 3 tiles) to enter the pyramid model is discussed in the case of irregular pulse, by logical operation on the detection of linear node. https://kns.cnki.net/KCMS/detail/11.2109.TP.20200302.1655.009.html
