DIFC-Net detects AI-generated images in unseen diffusion models, indicating improved detection capabilities.

The aim is to develop a robust framework to identify AI-generated images based on diffusion model behavior.
Developed DIFC-Net framework for analyzing diffusion inversion reconstruction behavior.
Utilized spatial discrepancy signals and latent diffusion trajectory for detection.
Conducted extensive evaluations across multiple unseen diffusion models.
Achieved 90.29% average AUC in detecting AI-generated images.
Outperformed existing state-of-the-art detectors in detection accuracy.
Maintained strong generalization across different generative models.
