| Summary: | Industrial anomaly detection plays a critical role in computer vision, driving advancements across various sectors. In recent works in this field, there are trade-offs between computational complexity and anomaly detection accuracy for effective deployment. To achieve both reduced latency and improved accuracy, we propose a simple reconstruction network that learns local clusters centered at core-features derived from PatchCore. By leveraging these features that represent local data distributions and their adjacent patch-features, our network effectively enhances anomaly detection along with reduced inference time. Specifically, the proposed reconstruction network is designed to reconstruct core-features from their neighbors, effectively acting as a denoiser for Neighbor Noise. So neighbor noise is defined as the distance between a core-feature and its adjacent patch-features, which can be regarded as a noise added to core-faeture. By reducing this noise, our network creates tightly clustered reconstruction of core-features and their neighbors, excluding reconstructions of anomaly features. Evaluated on MVTecAD and MPDD datasets, our approach outperforms existing methods in both inference efficiency and accuracy.
