| Abstract(in English) | We describe a method that can detect specific human behaviors even in crowded surveillance video scenes. Our proposed method uses a HOG descriptor and SVM classifier to detect people, and it tracks the regions that contain people, called human regions, by calculating two-dimensional color histograms. The method recognizes specific behaviors by the features of human region trajectories. It identifies human behaviors by estimating the similarities to the reference trajectory of each behavior in the trajectory feature space. Verification techniques such as backward tracking and calculating optical flows helped reduce false alarms. Experiments showed our system could recognize several specific behaviors robustly even in crowded scenes. |
