MVTec LOCO AD

The MVTec logical constraints anomaly detection dataset

Abstract

The MVTec logical constraints anomaly detection (MVTec LOCO AD) dataset is intended for the evaluation of unsupervised anomaly localization algorithms. The dataset includes both structural and logical anomalies. It contains 3644 images from five different categories inspired by real-world industrial inspection scenarios. Structural anomalies appear as scratches, dents, or contaminations in the manufactured products. Logical anomalies violate underlying constraints, e.g., a permissible object being present in an invalid location or a required object not being present at all. The dataset also includes pixel-precise ground truth data for each anomalous region.

More information can be found in our corresponding paper titled "Beyond Dents and Scratches: Logical Constraints in Unsupervised Anomaly Detection and Localization".
