| Abstract |
|
An active contour method is presented and applied to robust
iris tracking. The main strength of the method is that
the contour model avoids explicit "feature" detection: contours
are simply assumed to remove statistical dependencies
on opposite sides of the contour. The contour model is utilized
in particle filtering together with the EM algorithm.
The method shows robustness to light changes and camera
defocusing, and makes it possible to use off-the-shelf hardware
for gaze-based interaction
