Overview

This study introduces a Robust Anomaly Detection (RAD) dataset with free views, uneven illuminations, and blurry collections to systematically evaluate the robustness of current anomaly detection methods.

RAD

Following the mainstream unsupervised anomaly detection setting (MVTec), we collected a total of 286 normal samples, of which 213 are used for training, and the remaining 73 for testing. Additionally, 327, 293, 281, and 323 abnormal samples across the four categories are used for testing, respectively.

Data Collection

Normal scenarios depict a work platform with multiple metal holes, whereas the abnormal scenarios feature the work platform with foreign objects. To establish a comprehensive benchmark for anomaly detection robustness, we introduce different types of foreign objects onto the work platform, including bolts, cable ties, sponges, and tapes. Subsequently, the images are captured under various imaging noises, encompassing random viewpoints, illuminations, and imaging distances to replicate practical noise scenarios.

Annotation

Each abnormal sample has been accurately labeled.

Metrics

We choose AUROC, Max-F1 and AP as metric for image-wise anomaly detection. We choose AUROC, Max-F1, AP and AUPRO as metric for pixel-wise anomaly detection. You can find the code for calculating these metrics in eval_method.py.
