The result of the proposed eyelash segmentation algorithm: (a) iris image with eyelids removal, (b) grayscale image of (a), (c) the histogram of the region just below upper eyelid, (d) the histogram of the region just above lower eyelid, (e) the histogram-plot of the below upper eyelid and the above lower eyelid regions, where the black vertical dash line indicates the intensity threshold for eyelashes detection, and (f) the result of the proposed eyelash segmentation algorithm.
