Abstract

To handle the issues of low accuracy and lacking training samples in abnormal crowd behavior detection in public places, this paper proposed a method based on deep spatial-temporal convolutional neural networks. In view of the characteristics of crowd behavior in monitoring videos, it first designed a deep spatial-temporal convolution neural network for detecting abnormal crowd behavior by extending 2D convolution to the 3D space according to spatial features of static images and temporal features between the frames before and after the current frame. To locating abnormal crowd behaviors, this paper divided video frames into a number of sub-regions and obtained spatial-temporal samples of sub-regions. Then, it input the samples into the designed deep spatial-temporal convolutional neural network for training and classification, so as to detect and locate abnormal crowd behaviors. Meanwhile, to deal with the issue of lacking training samples when training the deep spatial-temporal convolutional neural network, a transfer learning method was designed to use datasets with more training samples to pre-train the network. Then it fine-tuned and optimized the network model in the datasets to be tested. Experimental results show that the detection accuracies on UCSD and subway open datasets are greater than 99% and 93% respectively.
