  • Real-Time Face Pose Estimation from Single Range Images

    We present a real-time algorithm to estimate the 3D pose of a previously unseen face from a single range im-age. Based on a novel shape signature to identify noses in range images, we generate candidates for their positions, and then generate and evaluate many pose hypotheses in parallel using modern graphics processing units (GPUs).
