A statistical feature based approach to distinguish PRCG from photographs ?
A method to distinguish photographic images and photorealistic computer graphics is proposed. A customized statistical feature, named texture similarity, is defined. Proposed method used Homomorphic filtering to highlight the image detail information. Proposed method is robust for content-preserving manipulations. Proposed method provides satisfactory detection accuracy and generalization capability.
