In view of the current eye tracking methods were too sensitive to conditions that face scale variations
partial occlusion of eye and head rotations in horizontality and verticality
which often resulted in tracking failure for the loss of objects. One eyes tracking method was proposed that was based on Kalman filter and improved Camshift algorithm. Firstly
predict the position of the eyes in the current image by Kalman filter; secondly
search the eyes region by Camshift iteration algorithm at the center of predicted position; thirdly
adjust the search window in the light of the symmetry of the of eyes; finally
update Kalman filter and the eyes templates. The experimental results show this method is robustness to those proposed conditions.
