| Abstract(in English) | We developed the human behavior recognition system by using surveillance camera. This system detects human behavior changing. I adapted the hybrid method which can change the nearest tracking method and particle filter method dynamically, so this system can track some humans who are overlapped. Because of Self Organizing feature Maps, this system can output the classification result without the learning step in advance. In this report, I defined that human walking condition is normal, and the human fighting condition is abnormal. As a result, the rate of false alarm in the walking data set is 1.8%, and the sensitivity rate in the fighting data set is 64.2% in all frames. I found that the most effective feature is the average of the optical flow direction (sine and cosine). |
