Simultaneous Estimation of Head Pose and Shape by Hierarchical Control System.
Junji Satake, Takeshi Shakunaga · 2002
The present paper proposes a simultaneous estimation of both human head pose and shape. When head pose is estimated for a generic face model, a considerable estimation error is generated by the shape difference between the model and the target face. In the proposed framework, a specific face model is gradually created for the target face by deforming the generic model based on an error analysis. These tasks are controlled by a hierarchical attention control system. Stable and efficient estimation is realized by switching the processes in a hierarchical control system. Experimental results show that the proposed system can simultaneously estimate head pose and shape for several persons. 1
