Abstract
We developed a fast and robust head pose and gaze estimation system. This system can detect facial feature points and estimate 3D pose angles and gaze direction in various conditions including changes in facial expression, partial occlusion, etc. The system needs only one face image as input and doesn't need any special devices such as blinking LED or stereo camera. Moreover, no calibration process is needed. It shows 95% of head pose estimation accuracy and 81% of gaze estimation accuracy (when the error margin is 15 degrees). The processing time is approximately 15ms/frame (Pentium4 3.2 GHz). Acceptable range of facial pose is within +/- 60 degrees in yaw (left-right) and within +/- 30 degrees in pitch (up-down).
