IntroductionIntroduction

Advanced image processing Advanced image processing algorithm for facial recognition algorithm for facial recognition

There are several techniques There are several techniques currently used in facial recognition:currently used in facial recognition:• EigenfaceEigenface• Edge mappingEdge mapping• Line edge mappingLine edge mapping

grouping pixels of a face edge map to line grouping pixels of a face edge map to line segments segments
