Head Tracking
The aim of this work is the development of a novel method for 3D head tracking in the presence of large head
rotations and facial expression changes. Tracking is
formulated in terms of color image registration in the texture map of a 3D
surface model. Model appearance is recursively updated via image
mosaicking in the texture map as the head orientation varies. The
resulting dynamic texture map provides a stabilized view of the face that
can be used as input to many existing 2D techniques for face recognition,
facial expressions analysis, lip reading, and eye tracking.
Parameters are estimated via a robust minimization procedure; this
provides robustness to occlusions, wrinkles, shadows, and specular
highlights.
