3D Head Trajectory using a Single Camera
Video surveillance applications need tools to track people trajectories. We present here a
new method to extract the 3D head trajectory of a person in a room using only one calibrated
camera. A 3D ellipsoid representing the head is used to track the person with a hierarchical
particle filter. This method can run in quasi-real-time providing reasonable 3D errors for a
monocular system.
