Abstract
A system and method for effectively extracting facial feature information from image data may include a facial feature detector configured to generate facial feature information. The facial feature detector may perform an eye-area vertical projection procedure for generating eye information and eyebrow information. The facial feature detector may utilize an eyebrow filter to detect eyebrow location coordinates and eyebrow slope characteristics. Similarly, the facial feature detector may utilize an iris filter to detect iris location coordinates. The facial feature detector may also perform a mouth-area vertical projection procedure for generating corresponding nose/nostril location information and mouth/lip location information.
