Image classification method based on semantic relation graph

The invention discloses an image classification method based on a semantic relation graph, and the method specifically comprises the steps: 1) preparing an image training sample set, and constructing the semantic relation graph according to the image training sample set; 2) building a network model of the image classification method based on the semantic relation graph according to the image training sample set and the semantic relation graph; 3) constructing a semantic correlation objective function; 4) constructing a local geometric structure consistency objective function; 5) constructing a total objective function according to the semantic correlation objective function and the local geometric structure consistency objective function; (6) training the network model built in the step (2) on a training sample set according to the total objective function built in the step (5); and 7) inputting an image to be classified into the network model trained in the step 6), and obtaining a prediction category of the
