Abstract: Many crowd analysis methods are developed in computer vision area. In this work we present an approach to explore characteristics inherent to human crowds – proxemics, and neighborhood relationship – for extract crowd features. We propose a crowd flow filtering approach for calibrated cameras that can be coupled to any generic optical flow method, and also a method to anomaly detection and localization using machine learning techniques. Both approaches were tested on publicly available datasets involving human crowded scenarios.
