Zongcai Ruan · Jisuanji gongcheng · 2012
A method of head behavior recognition based on the analysis of trajectory is presented.It detectes and trackes the face automatically,and calculates parameters of the trajectory of the face.It can achieve the behavior recognition of the head by parameters' data statistics and analysis.For the problem of the exchange of the long axis and the short axis of the tracking window at the case of up head and down head,it proposes an improved algorithm of the angle between the major axis of the tracking box and the vertical axis.Experimental result shows that the problem of the exchange of the long axis and the short axis have been successfully resolved,and the algorithm can recognize the behavior of the head correctly.
