Detecting Crowd Features in Video Sequences

We propose a new methodology to detect social aspects of crowds in video sequences based on pedestrian features, which are obtained through image processing/computer vision techniques. The main idea is to apply and extend the concepts of Fundamental Diagram (FD) with more features, such as grouping and collectivity. Using crowd features we identify the crowd type and the main characteristics. In addition, we also investigated two further results: the visual assessment of people in real video sequences in order to detect crowd characteristics, and the usage of our method to detect similarity of crowds in videos.
