Researchers have developed novel approaches to zero-shot anomaly detection, a technique for identifying defects in unseen categories without specific training. One method, AVA-DINO, utilizes dual specialized branches for normal and anomalous patterns, adapting frozen visual features to exploit the asymmetric distributions of normal versus anomalous data. Another approach, AnomalyClaw, frames anomaly judgment as a multi-round refutation process using a library of tools to verify against normal-sample references, improving the reliability of vision-language models for cross-domain anomaly detection.
