Abstract
A simple procedure that uses only three feature points to
infer 3-D head motion from consecutive video frames is
presented. In this procedure, a feature triangle formed
using the three feature points is automatically calibrated,
and an iterative method that simulates steepest descent
method is applied to estimate one's head motion. A pre-diction
algorithm is adopted in occasional cases where
the estimated result is not acceptable. This procedure has
been applied to live video with an update rate of 7
frames/sec (250 frames/sec without feature extraction) on
a Pentium-II 233MHz PC, independent of cameras and
users.
