SimpleNet: A Simple Network for Image Anomaly Detection and Localization

2 code implementations CVPR 2023 Zhikang Liu, Yiming Zhou, Yuansheng Xu, Zilei Wang

SimpleNet consists of four components: (1) a pre-trained Feature Extractor that generates local features, (2) a shallow Feature Adapter that transfers local features towards target domain, (3) a simple Anomaly Feature Generator that counterfeits anomaly features by adding Gaussian noise to normal features, and (4) a binary Anomaly Discriminator that distinguishes anomaly features from normal features.
