Locating driver’s eyes exactly firstly to judge driver’s eye state.Then by counting eye area and area’s reduction extent

noting eye’s continual closure time and closure frequency to detect driver’s eye fatigue state.Secondly

by skin color segmentation in RGB space

removing the object connected to the border and minishing the range of eye area gradually together with shape validation to locate driver’ eye

and then the eye closure times and time are computed.The test proves this method is simple and fast

and it can’t be influenced by complex background

faces of different skin color or guise.
