摘要

The method involves producing a digital image by performing a point to point subtraction between a reference image taken before or after eye blink and an image taken during the blink. The presence of eyes in the digital image is detected, where eyes are constituted by separated speckles. The center of each speckle is determined, where the coordinates of the centers constitute the positional reference of the face in the reference image.
