| Abstract |
Playing a vitally important role in the operation of intelligent video surveillance system and smart city, video anomaly detection (VAD) has been widely practiced and studied in both industrial circles and academia. In the present study, a new anomaly detection method is proposed for multi-level memory embedding. According to the novel method, the feature prototype of the sample is stored in the memory pool, which enhances the diversity of the sample feature prototype paradigm. Besides, the memory is embedded in the decoder in a hierarchical integrating manner, which makes the feature information of the object more complete and improves the quality of features. At the end of the model, modeling is performed for the channel relationship between the features of the object in the channel dimension, thus making the model capable of more efficient anomaly detection. This method is verified by conducting evaluation on three publicly available datasets: UCSD Ped2, CUHK Avenue, ShanghaiTech. © 2023, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature. |
