Abstract
This paper presents a method to improve face detection by locating
eyes in an image using infrared (IR) light. IR light produces Red-Eye
effect making the pupil to shine more than in normal lighting con-
ditions. The location of the eyes and the face contour are computed
from the IR images using a collection of image processing techniques.
The algorithm operates on gray images under a variety of skin tones,
eye colors, angles, and illuminations. The developed method analyzes
two consecutive frames where the first one is taken under regular illu-
mination with no IR and the second one using IR in order to facilitate
eye detection for subjects wearing glasses.
