Abstract(in English) | This paper presents a method for detecting abnormal motion at an escalator scene, in which the movement of the escalator provides a dynamic background. This method is based on the use of spatio-temporal features obtained by space-time patches. Our approach consists of three steps; dynamic background modeling by using the Gaussian mixture model, human region detection based on RealAdaboost, and calculation of irregularity measure by using weighted space-time gradients. The proposed method can detect abnormal motions from a scene with a dynamic background, that would be difficult to detect with the conventional method using CHLAC (Cubic Higher-order Local Auto-Correlation) features. Our experimental results show that using our method has about 27% higher performance than that of the conventional method. |
