摘要
In this paper, we propose a novel and robust fall detection system by using a density method for modeling a fall event as a function of certain video feature. 3-D head velocity and human shape information are extracted as feature and three types of density model, single Gaussian, mixture of Gaussians and Parzen window method, are constructed for modeling the density of fall with respect to the extracted video feature. Falls are then detected according to the corresponding obtained density model and the success of the method is confirmed on real video sequences.
