Abstract

The invention belongs to the field of behavior recognition, particularly relates to a group behavior recognition model based on progressive relation learning and a training method thereof, and aims tosolve the problem of low group behavior recognition accuracy in the prior art by mining key relations in group behaviors. The group behavior recognition model comprises a semantic relation graph generation network, a reinforcement learning network and a softmax classification layer. The network parameters of the other network are trained on the basis of alternately keeping the network parametersof one network unchanged / removing the network for the semantic relation graph network and the reinforcement learning network until a preset training end condition is met, and the trained group behavior recognition model is obtained. The group behavior recognition model obtained through the method has higher recognition accuracy.

Description

technical field [0001] The invention belongs to the field of behavior recognition, and in particular relates to a group behavior recognition model based on progressive relational learning and a training method thereof. Background technique [0002] Behavior recognition has a wide range of applications in the fields of intelligent monitoring, human-computer interaction and automatic driving. According to the number of individuals involved, behavior recognition can be divided into single individual behavior recognition, double individual behavior recognition and group behavior recognition. Group behavior recognition has the characteristics of many parameter individuals, not only needs to model the spatiotemporal dynamics of each individual, but also needs to model the complex interaction relationship between individuals. At the same time, group behavior videos are rich in a large amount of semantic noise, and the category of group behavior is usually only determined by a fe...
