An image feature segmentation method based on a graph convolutional network

The invention discloses an image feature segmentation method based on a graph convolutional network. The method comprises steps of segmenting the preprocessed image by using a uniform grid; Constructing a directed unweighted graph taking the central image block as a vertex, and writing an adjacent matrix, a feature matrix and a degree matrix of each node corresponding to the graph by utilizing therelationship of the image blocks; Setting a weight matrix according to priori knowledge, and using a formula f (X, A) = D-1*A*X*W to carry out first-layer graph convolution on the graph; Updating thenode information by using a convolution result and taking the node information as an initial value of the next layer of convolution; And constructing a new image again, carrying out convolution, andcarrying out layer-by-layer iteration until the feature segmentation of the whole image is completed. According to the method, before a graph convolution network is made, an image is segmented by using uniform grids, the calculation amount of convolution operation is reduced to a great extent, and the accuracy of feature segmentation is improved by adopting a layer-by-layer iteration method. According to the method, image feature segmentation is carried out by using the graph convolutional network, so that the problem that the convolutional neural network cannot process irregular images is solved, the segmentation effect is greatly improved, and an optimization effect on a feature segmentation result is achieved.
