How DiffPathV2 Achieves Zero‑Shot Image Anomaly Detection with 94.9% AUROC

This article breaks down the ICCV 2025 paper "Zero‑Shot Image Anomaly Detection Using Generative Foundation Models," explaining how DiffPathV2 leverages diffusion model denoising trajectories, six‑dimensional score errors, and SSIM weighting to detect out‑of‑distribution images without any task‑specific training, achieving state‑of‑the‑art AUROC scores across multiple benchmarks.
