On Computer Generated Image Recognition Method Based on CNN

In order to solve the problem low recognition rate for Computer Generated images (CG) and Photographs (PG), an improved convolution neural network method is proposed to realize the recognition of CG and PG. This method first set up the two-classification model of the convolution neural network for the recognition problem and the VGG-19 network structure is selected as the basis to establish different models. This method innovatively introduces migration learning and saves training time and massive computing resources. Finally, softmax classifier is used to classify. The experimental results show that the accuracy of the proposed method for PG image recognition is up to 92%, and the recognition speed is faster. Compared with other methods, the method has the highest recognition accuracy and demonstrates the feasibility and effectiveness of the proposed method.
