Tracking Eyelid Position During a Stimulated Blink using Image Processing (image) Medical University of South Carolina Share Print E-Mail Caption The positions of the right (red) and left (blue) eyelids during a stimulated blink are tracked over time using image processing. The technique produces rapid, non-invasive, and objective measurements of blink parameters, making it a useful tool for assessing neurological function.
