Key Highlights

• A relation neural network based on few-shot learning to capture the underlying similarities between real and artificial images.
• The network learns a tailored difference function to effectively compare images for artificialness arising from GAN-based generation.
• For comparison, hierarchical clustering is used to evaluate the quality of image feature separation between real and artificial images.
• The proposed relational network achieves a 61.4% F1-score in distinguishing real and artificial medical images on a blinded test-set provided and evaluated by ImageCLEF.
