【Abstract】 Aiming at the shortcomings of current various eye tracking methods,a rapid eye tracking algorithm based on precise positioning iris is proposed.Firstly,the detector based on AdaBoost algorithm is used to position iris,and susan operator is used to eliminate the influence of eyeball-like factors.The improved CamShift algorithm based on multi features fusion is used for eye tacking with the template of iris region and analysis of the feature of object and noise’s saturation.The experimental results show that this method can precisely track iris,with rapid speed,low error rate,it meets the requirements of accuracy,robustness and real-time.更多还原
