I have done the same experimentation again, and it gives the video ...

This is a height degrees of freedom (8-dof) correspondence of images.
In the video, the projective transform is shown. There's also the
mosaics of the 3D head tracking, and the reconstruction of the motion,
with POV-Ray. I also displayed the optical-flow between successive
images. The head pose is obtained, even for very large movements !

I added some information to the video, so that you can understand ...

I hope it help =)

Best regards,
