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.
