Beyond Semantic Features: Pixel-level Mapping for Generalized AI-Generated Image Detection

AAAI 2026technical

The rapid evolution of generative technologies necessitates reliable methods for detecting AI-generated images. A critical limitation of current detectors is their failure to generalize to images from unseen generative models, as they often overfit to source-specific semantic cues rather than learni
