Abstract

Embodiments of the present invention provide a group behavior analysis method and device, the method comprising: constructing a target loss function based on a network loss function and a variance minimization method, and constructing a target supervision model based on the target loss function through a deep supervision method; Based on the multi-channel encoder, the multi-channel decoder, and the target supervision model, a target deep neural network is constructed; the group behavior analysis is performed through the target deep neural network to determine the group behavior state according to the analysis result. Using the group behavior analysis method provided by the present invention can effectively improve the accuracy and reliability of the analysis results, improve the analysis efficiency of group behavior, and reduce the consumption of human resources.

Description

technical field [0001] The invention relates to the field of behavior analysis, in particular to a group behavior analysis method and device. Background technique [0002] With the rapid development of urbanization, the number of occurrences of abnormal group behaviors has also increased significantly, and the occurrence of abnormal group behaviors usually poses a hazard to social public safety. Therefore, how to analyze group behavior has become particularly important [0003] At this stage, the analysis of group behavior is usually carried out by staff. Specifically, firstly, real-time image frames of corresponding places can be acquired through monitoring equipment installed in various public places. Then, the staff can monitor the images captured by each monitoring device, and manually analyze whether abnormal group behaviors occur based on the monitored images, so as to deal with the abnormal group behaviors according to the analysis results. However, manual group be...
