Paper Abstract:	A method is proposed for detecting human iris location and size in digital image given some point lying inside the pupil. Method is based on construction of histogram projections of local brightness gradients. Local maxima of these histograms are then treated as possible positions of the sides of pupil and iris. Each combination of maxima yields a hypothesis of how pupil and iris are located in image and most plausible one is selected. Method has low calculation cost.
