Abstract

The present invention discloses an edge detection method based on cellular automata theory, which includes the following steps: S1: acquire the original image; S2: perform binarization processing on the original image to obtain a binarized image; S21: according to the binarization The energy distribution of the image is divided into regions; S22: digitally represent the region; S23: code the digitally represented region; S231: calculate the selected region to obtain the number of adjacent matrices; S232: select the region represented by a specific number; S3: Perform edge feature extraction on the binarized image according to the cellular automata operation rules with intermediate continuous samples to obtain the target image. Compared with the image measured by the Canny algorithm, the edge detection method based on the cellular automata theory of the present invention detects the image edge, and the target image is softer, the details are clearer, the noise in the processing process is small, and the amount of calculation is relatively small. less.

Description

technical field [0001] The invention relates to the technical field of image edge detection, in particular to an edge detection method based on cellular automata theory. Background technique [0002] As a basic problem in the image field, edge detection can provide help and reference for many traditional technical fields, such as salient object detection, image segmentation and skeleton extraction. At present, the Canny algorithm is commonly used to detect edges, such as figure 1 and figure 2 as shown, figure 1 for the original image, figure 2 It is an image obtained by using the Canny algorithm to detect the edge of the image. However, the softness of the image obtained by using the Canny algorithm to detect the edge of the image is poor, and the amount of calculation is large, and the noise generated during the processing is also large. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention discloses a method of edge d...
