Fault-Guided Cross-Layer Prediction for Unsupervised Anomaly Detection

Read the original on arXiv Computer Vision →

The paper introduces a single‑class unsupervised anomaly detector that leverages cross‑layer predictions within a frozen vision transformer. By treating transformer depth as a sequence of discrete transitions, a directed predictor learns block‑to‑block hidden‑state transitions, revealing fault lines that separate stable depth segments. Using a bounded foreground prior calibrated only on training data, the method achieves state‑of‑the‑art AUROC scores on MVTec‑AD, VisA, and Real‑IAD datasets.

Training-Free Logical and Structural Anomaly Detection via Calibrated Fusion

The paper introduces a training‑free anomaly detector that simultaneously handles structural and logical defects by calibrating heterogeneous anomaly cues with statistics from normal images. This calibration aligns frozen representations, allowing their fusion without extra training or part‑level supervision. The resulting method achieves state‑of‑the‑art AUROC scores on MVTec‑LOCO and remains competitive on MVTec‑AD.

See More, Detect Less? Taming Information Leakage in Multi-View Anomaly Detection

The paper identifies a problem in multi‑view anomaly detection called cross‑view information leakage, where fusing multiple inspection views can cause normal features to mask anomalies during reconstruction. To address this, the authors propose GLAD, a framework that uses a Global‑Local Attention Driven approach, combining vision foundation model features with two fusion modules: Multi‑view Merging Attention for local, weighted fusion and Object‑Guided Attention for global context aggregation. Experiments on Real‑IAD and MANTA‑Tiny demonstrate that GLAD outperforms existing methods across various metrics, underscoring the importance of restricting information flow to preserve the reconstruction gap.
