Study on driver´s mouth segmentation and location based on color space

Driver´s fatigue and spirit distraction has become one of the most important causes for traffic accidents. The detection of drivers mouth state could offer a useful distinguish criterion for judge whether the driver is fatigue or spirit distraction. Based on our research foundation, a new method with certain environmental robustness for driver´s face detection and location, mouth detection and location is proposed based on color space. This method could be establishing a good step for further research on the capture of driver´s mouth state.
