| Abstract(in English) | This paper presents a method to detect abnormal motion by using spatio-temporal features. At first, silhouette images obtained from the backgrouund subtraction are separated into the upper part and the lower part. Each part is separated into some blocks so that the number of pixels in each block may be distributed equally. Next, the fourier transform is applied to time series data consisting of the pixel density in each block and the motion features are detected. In addition to the motion features, the shape features are detected by calculating the mean and the variance of the pixel density in each block. The classifier using one class SVM is created by leaning feature vectors generated from this process. Our method can detect both dynamic abnormal motions and static ones. In this experiment, walking, running or stopping was detected as normal motion,and the others were abnormal. The validity of the method was confirmed by experimental results. |
