Abstract: Now a days the death injuries are increased as the rate of road accidents are more. One of the main cause is due to driver fatigue. In this paper the detection of drowsy driver is based on closed or opened eye condition and displaying warning message accordingly. Detection of closed and opened eye condition is done by observing the blink pattern and eye movement. Real time detection of driverís eyes is to be processed using image processing in MATLAB to detect weather the eye remains closed for more than fixed duration which indicates the condition of fatigue and raises an alarm which could prevent a collision. Even though if the driver is drowsy, continues alarm raises, if number of raised alarm crosses certain limit then the vehicle will be made to slowdown and stopped.
