Long-Tailed Online Anomaly Detection dataset for identifing defect regions of a given image.

Anomaly detection (AD) identifies the defect regions of a given image. Recent works have studied AD, focusing on learning AD without abnormal images, with long-tailed distributed training data, and using a unified model for all classes. In addition, online AD learning has also been explored. We expand in both directions to a realistic setting by considering the novel task of long-tailed online AD (LTOAD).
