Driver’s Face Detection Using Space-time Restrained Adaboost Method
Tong Liu · KSII Transactions on Internet and Information Systems · 2012
Face detection is the first step of vision-based driver fatigue detection method.Traditional face detection methods have problems of high false-detection rates and long detection times.A space-time restrained Adaboost method is presented in this paper that resolves these problems.Firstly, the possible position of a driver's face in a video frame is measured relative to the previous frame.Secondly, a space-time restriction strategy is designed to restrain the detection window and scale of the Adaboost method to reduce time consumption and false-detection of face detection.Finally, a face knowledge restriction strategy is designed to confirm that the faces detected by this Adaboost method.Experiments compare the methods and confirm that a driver's face can be detected rapidly and precisely.
