Image edge detection method based on Spiking-convolution network model

Abstract

The invention discloses an image edge detection method based on a Spiking-convolution network model, which belongs to the technical field of image processing and solves the problem that a method in the prior art only simulates the spatial hierarchical structure of a biological nervous system, but lacks interpretation to time characteristics. The image edge detection method disclosed by the invention comprises the following steps: creating the Spiking-convolution network model of a convolution structure having an input layer, a Spiking-convolution layer and an output layer based on an information processing connection manner of a visual hierarchical structure; using a Laplace-Gauss operator and a Gauss difference operator as a filter of the Spiking-convolution layer of the created Spiking-convolution network model of the convolution structure to form a Spiking-convolution algorithm based on the operators; obtaining an image, encoding gray value pixels of the image into Spiking neurons to serve as the input layer of the Spiking-convolution network model; applying the Spiking-convolution algorithm based on the operators to the Spiking-convolution network model, carrying out pulse convolution on the input layer, and then recreating and outputting the edge of the image according to a Spiking threshold ignition model. The image edge detection method disclosed by the invention is applied to image pre-processing, characteristic extraction and edge detection and relates to neural networks, machine learning and Deep Learning.
