Abstract: Driver in-alertness is an important cause for most accident related to the vehicles crashes. Driver fatigue resulting from sleep deprivation or sleep disorders is an important factor in the increasing number of the accidents on today?s roads. Drowsy driver warning system can form the basis of the system to possibly reduce the accidents related to driver?s drowsiness. The purpose of such a system is to perform detection of driver fatigue.
