Computer input with human eves only using blink detection based on Gabor filter

A method for computer input with human eyes only using blink detection based on Gabor filter is proposed. In order to detect eye blinking, we utilize top and bottom of eye arcs. Distance between top and bottom of these arcs is equal with percentage of open-closed eye. I f this distance is maximum, it sign that eye is open 100%. Otherwise, i f this distance is close to zero, it means that eye is open 0% (or eye closed).
