Abstract
A dynamic eye tracking system to track movement of an eye including the steps of detecting if a neighbor exists about the eye over a predetermined amount of time and forming a boundary for the neighbor. Eye candidates are tracked and a determination is made if the eye candidates are beyond the boundary defined by the detected neighbor.
Claims7
A dynamic eye tracking method to track movement of an eye in video images from a camera, said method comprising:
- providing a camera;
- using a computerized eye state monitor having a computer readable medium;
- detecting if a neighbor exists about the eye using initial coordinates of the eye for over a predetermined amount of time within a predefined area;
- forming a boundary for said neighbor within said predefined area;
- tracking potential eye candidates;
- and
- determining if said eye candidates are beyond the boundary and eliminating the eye candidates outside the boundary defined by the detected neighbors within said predefined area.

A dynamic eye tracking method to track movement of an eye in video images from a camera, the method comprising:
- providing a camera;
- using a computerized eye state monitor having a computer readable medium;
- executing in sequence any one of a series of eye candidate subroutines to determine if an acceptable eye candidate exists;
- and
- for each subroutine then determining if said eye candidate is beyond or within a boundary defined by said neighbors within a predefined area.
