Kalman filter combined with Adaboost recognize head gesture for human-intelligent wheelchair interaction

Head gesture is an important intelligent human-wheelchair interaction approach,and the head gesture recognition is an important aspect of the interactions.A new head guests recognition to control the intelligent wheelchair presents in this paper,Kalman filter forecast the lips position detected by Adaboost algorithm may be appeared in the next frames first,and then detect the lips in the next frame.Compare the lips window position with a fixed rectangle to confirm the head gesture correspondingly.Kalman filter overcome detect all the possible lips position by just use the Adaboost algorithm in every frame,greatly improve the lips detection precision and reduce the detection time,solve the wheelchair's time delay during the head guests controlling.
