Abstract

We present an investigation into locating nose tips in 2D images of human faces. Our objective is conference-room gaze-tracking, in which a presenter can control a presentation or demonstration by gaze from a distance in the range 2m to 10m. In a first step towards this, we here consider faces in the range 150cm to 300cm. Head pose is the major contributing component of gaze direction, and nose tip position within the image of the face is a strong clue to head pose. To facilitate detection of nose tips, we have implemented a combination of two Haar cascades (one for frontal noses and one for profile noses) with a lower failure rate than existing cascades, and we have examined a number of ”hand-crafted ferns” for their potential to locate the nose tip within the nose-like regions returned by our Haar cascades
