Pattern recognition method can be used to discriminate photo images from computer graphics. In this paper, the model is established based on statistical moment features and statistics extracted from Color Filter Array(CFA). This model can capture different correlation of image content between photo images and Computer Graphics(CG). To evaluate the performance of the scheme, the model was further tested applying to the Columbia photographic images and photorealistic computer graphics dataset. Artificial neural network is chosen as a classifier to train and test the given images. Experimental results demonstrate that the model performs higher degree of accuracy, indicating that the proposed approach has better stability and possesses promising capability in discrimination of computer graphics from photo images.
