“…e model proposed in this paper is mainly used in multisensor monitoring network to achieve multiobject detection and association and to analyze the behavior trend of the object. In order to evaluate the performance of our proposed abnormal behavior detection algorithm, the training set uses the international common behavior recognition data: UCSD, KTH,UCF101, and HMDB5 [31][32][33][34][35]. e KTH database includes six types of behaviors with 25 different pedestrians in four scenarios, namely, walking, running, waving, jogging, boxing, and handclapping, where the camera of these samples is relatively fixed and the background is simple; UCF101 and HMDB5 are complex datasets containing a large number of behavior categories, most of the data comes from video clips, pedestrian movement is complex, the angle of view changes greatly, and there are a lot of multiperson interaction.…”
