| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | We developed a method for detecting real-time anomal movement for use in monitoring systems. Our method is based on learning the position and the moving direction of people. The position and moving direction of people contains important information that can be used for anomal detection; therefore, the tracks or the flo histograms are used as features for anomal detection in conventional anomal detection methods. However, it is difficult to use both the position information and the moving direction information simultaneously because of the poor stability and the high calculation cost. Therefore, we use the two types of information by extracting the spatial and temporal average of the optical flow so that the time for the movement vector continuously appears. We used an incremental SVM modified for 1-class as the discrimination method, which enabled the online learning to be unsupervised. Experiments showed that when using our method with QVGA-size video as the input, anomal scenes can be detected and that real-time computation is possible. |
