A new benchmark called DOCFORGE-BENCH has been introduced to evaluate document forgery detection methods in a zero-shot setting, meaning without domain-specific training data. The benchmark found that current methods suffer from significant calibration failures, achieving moderate AUC scores but near-zero F1 scores due to the small proportion of tampered pixels in document images. Adapting a single threshold on a small number of domain images can recover a substantial portion of the performance gap, indicating that threshold adaptation, rather than retraining, is crucial for practical deployment. The study also highlights the absence of benchmarks covering generative AI-based document forgeries. AI
