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