PGC: Peak-Guided Calibration for Generalizable AI-Generated Image Detection

Researchers introduced Peak-Guided Calibration (PGC), a new framework for generalizable AI-generated image detection.

PGC calibrates global image-level decisions using peak-focused local features, aiming to capture the most discriminative clues.

The method achieved state-of-the-art results across multiple benchmarks, including stronger cross-model detection performance.

The work also introduces CommGen15, a tougher 15-model benchmark designed to better reflect real-world generative threats.
