Head Pose Estimation in Multi Camera Environment

We develop methods for estimating the head orientation of people from multiple distant cameras integrated with real-time tracking.

Simultaneous tracking and head pose estimation enables detailed reporting on attention patterns of people visiting an architectural space or during natural interactions. Main challenges are the very low resolution and non-frontal views of the faces as captured by distant cameras.
