Abstract: | A method is proposed to detect human iris location and size in digital image given some point lying inside the pupil. The
method is based on construction of histograms, or projections of local brightness gradients, and combinations of projections’
maxima being regarded as possible locations of pupil and iris borders. The method is notable for its low computational complexity
and high tolerance to noise. |
