Anomaly detection for human action aims to identify action patterns that deviate from the expected behavior. Collecting anomalous data is challenging, so prior methods learn normal data distributions for one-class classification. However, these methods require large amounts of normal data and fail to detect anomalies in actions with limited samples. In this study, we propose a method leveraging few normal samples, using contrastive learning for representation and calculating similarity during inference to detect anomalies. The experimental results demonstrate the effectiveness. |
