Abstract
This chapter proposes a fully automatic framework for real-time human head pose estimation from a monocular image based on geometric approach. Our method starts with Constraint Local Model-based (CLM-based) facial feature tracking. Combined with tracked facial feature locations and a statistical 3D human face model pre-captured from Kinect device, 3D translation and 3D orientation of head pose are estimated by Pose from Orthography and Scaling with Iterations (POSIT) algorithm. Since both CLM-based facial feature tracking and POSIT algorithm are fast, our method can achieve real-time head pose estimation with more than 15 frames/s (fps) in an Intel i5-3230 CPU 3.0 GHz processor without GPU acceleration. By using Kinect’s head pose estimation results as ground truth data, our estimation results show that head location and orientations can achieve tracking accuracy within 2 cm and 5° standard deviations, respectively.
