Hierarchical Gaussian Mixture Normalizing Flow Modeling for Unified Anomaly Detection

1 code implementation20 Mar 2024 Xincheng Yao, Ruoqi Li, Zefeng Qian, Lu Wang, Chongyang Zhang

In this paper, we propose a novel Hierarchical Gaussian mixture normalizing flow modeling method for accomplishing unified Anomaly Detection, which we call HGAD.

Focus the Discrepancy: Intra- and Inter-Correlation Learning for Image Anomaly Detection

1 code implementation ICCV 2023 Xincheng Yao, Ruoqi Li, Zefeng Qian, Yan Luo, Chongyang Zhang

Humans recognize anomalies through two aspects: larger patch-wise representation discrepancies and weaker patch-to-normal-patch correlations.

Explicit Boundary Guided Semi-Push-Pull Contrastive Learning for Supervised Anomaly Detection

1 code implementation CVPR 2023 Xincheng Yao, Ruoqi Li, Jing Zhang, Jun Sun, Chongyang Zhang

In this way, our model can form a more explicit and discriminative decision boundary to distinguish known and also unseen anomalies from normal samples more effectively.
