PNUNet: Anomaly Detection using Positive-and-Negative Noise based on Self-Training Procedure
This addresses the problem of detecting anomalies in images, which is important for applications like quality control or security, but appears incremental as it builds on existing noise-based and self-training methods.
The paper tackles anomaly detection in images by proposing PNUNet, a framework that uses positive-and-negative noise with self-training to achieve significant performance improvements on benchmark datasets.
We propose the novel framework for anomaly detection in images. Our new framework, PNUNet, is based on many normal data and few anomalous data. We assume that some noises are added to the input images and learn to remove the noise. In addition, the proposed method achieves significant performance improvement by updating the noise assumed in the inputs using a self-training framework. The experimental results for the benchmark datasets show the usefulness of our new anomaly detection framework.
