Head Pose Estimation Without Manual Initialization
Paul Fitzpatrick · 2000
Abstract. This paper describes a fully automatic system for recovering the rigid components of head pose. It follows the conventional approach of tracking pose changes relative to a reference configuration. Rather than being supplied manually, here the reference configuration is determined by directly estimating pose from the image when the head is close to a frontal presentation. Tracking of pose is done in an intermediate coordinate system which minimizes the impact of errors in estimates of the 3D shape of the head being tracked. 1
