摘要: 面对复杂场景下异常事件检测的准确率偏低的情况,本文提出一种基于深度学习的异常事件检测方法,并将此方法扩展为异常事件分类方法.利用神经网络模型提取特征,将群体发散聚集事件,群体密集聚集事件,群体逃散事件和追赶事件这4种异常事件进行检测和分类.通过PKU-SVD-B测试集对训练出来的模型进行测试实验,并在UMN数据集上与几种方法做了对比实验,验证了本文提出的基于深度学习的异常事件检测算法,在适应多种不同场景的前提下,对多种异常事件检测的准确率很高,表明训练出来的模型对异常事件检测具有极强的泛化能力.

Abstract: Faced with low accuracy of abnormal event detection in complex scenarios, this paper proposes an abnormal event detection based on deep learning in various public scenes and multiple types of anomalies, and the method has been extended to an abnormal event classification method.The neural network model is used to extract features, and the four kinds of abnormal events, such as group divergence aggregation events, group intensive aggregation events, group escape events and catch-up events, are detected and classified.Test the trained model with PKU-SVD-B test set, compared with various methods on the UMN datasets, and verify the algorithm of abnormal event detection based on deep learning proposed in this paper.Under the premise of adapting to different scenarios, various abnormal events are detected.The high accuracy rate indicates that the trained model has strong ability to generalize abnormal event detection.
