SimpleNet: A Simple Network for Image Anomaly Detection and Localization [PDF]
Computer Vision and Pattern Recognition, 2023 We propose a simple and application-friendly network (called SimpleNet) for detecting and localizing anoma-lies. SimpleNet consists of four components: (1) a pre-trained Feature Extractor that generates local features, (2) a shallow Feature Adapter that ...

Towards Total Recall in Industrial Anomaly Detection [PDF]
Computer Vision and Pattern Recognition, 2021 Being able to spot defective parts is a critical component in large-scale industrial manufacturing. A particular challenge that we address in this work is the cold-start problem: fit a model using nominal (non-defective) example images only.

Anomaly Detection via Reverse Distillation from One-Class Embedding [PDF]
Computer Vision and Pattern Recognition, 2022 Knowledge distillation (KD) achieves promising results on the challenging problem of unsupervised anomaly detection (AD). The representation discrepancy of anomalies in the teacher-student (T-S) model provides essential evidence for AD.

Multi-Perspective Anomaly Detection [PDF]
Sensors, 2021 Anomaly detection is a critical problem in the manufacturing industry. In many applications, images of objects to be analyzed are captured from multiple perspectives which can be exploited to improve the robustness of anomaly detection. In this work, we build upon the deep support vector data description algorithm and address multi-perspective anomaly ...
