| Abstract(in English) | This paper proposes a new method for extracting abnormal scene in the video of periodic machinery operations. Firstly, we segment the video into periods and extract STIPs (Space-time Interest Points). Then, we examine frequency of appearance of STIPs to determine ROIs (regions of interest). After the calculation of features in the ROIs, abnormality of each segment is estimated by 1 class SVM (1 class Support Vector Machine). We conducted some experiments to compare the proposed method with conventional methods using PCA (Principal Component Analysis) and confirmed that our method is sensitive to the variation of the machinery motion and robust against background and illumination variations. |
