Models have been trained on the 300W-LP dataset and have been tested on real data with good qualitative performance. In between, if you have face update, you can also update the correlation face model to local predict the small step/baseline pose motion with larger varance. More speciﬁcally, we ﬁrst estimate the head pose using a deep Convolutional Network (ConvNet) directly from face image. Head Pose Estimation : The main objective of this task is to find the relative orientation (and position) of the human’s head with respect to the camera.

Argyros, "3D head pose estimation from multiple distant views", British Machine Vision Conference, London, UK, 7-10 September, 2009. There are two major approaches used to estimate head pose. They define the object’s rotation in a 3D environment. Pitch is 0 to 4 because you can divide the distance between eyes and lips into 4 units where one unit is between lips to nose-tip and 3 units between nose-tip to eyes. Particularly, it means detecting the head’s Euler angles – yaw, pitch and roll. 65° on average for a single Head pose estimation (HPE) has been widely applied in human attention recognition, robot vision and assistant driving.

The 6DOF head pose was estimated using pose from orthography and scaling with iterations (POSIT) where a statistical anthropometric 3D rigid model is used as an approximation of the human head, combined with active appearance models (AAM) for facial features extraction and tracking. In particular, in automotive context, head pose estimation is one of the key elements for attention monitoring and driver behavior analysis. S. Theoretically, this can be accomplished by detecting head curvature in the upper portion of the image. So, the head pose estimates can provide information on which direction the human head is facing. RGB-based head pose estimation is difﬁcult when illumina-tion variations, shadows, and occlusions are present.
