Multi-Camera Based Social Network Analysis

Social network analysis is a popular topic in social science. However, it needs a lot of human labor to get the information in psychological analysis. In this paper, we propose a multi-camera based evaluation system which can automatically track and recognize the human activities in an environment, and then build the corresponding social network and personality graphs. The proposed system contains three major parts: human detection, social behavior detection, and social interaction analysis. Experimental results show that the proposed system can discover the social network through analyzing people´s social interactions and provide a good result approximated to ground truth.
