Customizing Visual-Language Foundation Models for Multi-modal Anomaly Detection and Reasoning

1 code implementation17 Mar 2024 Xiaohao Xu, Yunkang Cao, Yongqi Chen, Weiming Shen, Xiaonan Huang

In addition, we unify the input representation of multi-modality into a 2D image format, enabling multi-modal anomaly detection and reasoning.

Dual-path Frequency Discriminators for Few-shot Anomaly Detection

no code implementations7 Mar 2024 Yuhu Bai, Jiangning Zhang, Yuhang Dong, Guanzhong Tian, Liang Liu, Yunkang Cao, Yabiao Wang, Chengjie Wang

We consider anomaly detection as a discriminative classification problem, wherefore the dual-path feature discrimination module is employed to detect and locate the image-level and feature-level anomalies in the feature space.

Collaborative Discrepancy Optimization for Reliable Image Anomaly Localization

1 code implementation IEEE Transactions on Industrial Informatics 2023 Yunkang Cao, Xiaohao Xu, Zhaoge Liu, Weiming Shen

CDO introduces a margin optimization module and an overlap optimization module to optimize the two key factors determining the localization performance, i. e., the margin and the overlap between the discrepancy distributions (DDs) of normal and abnormal samples.

Anomaly Detection

Informative knowledge distillation for image anomaly segmentation

1 code implementation Knowledge-Based Systems 2022 Yunkang Cao, Qian Wan, Weiming Shen, Liang Gao

However, rare attention has been paid to the overfitting problem caused by the inconsistency between the capacity of the neural network and the amount of knowledge in this scheme.
