Abstract: Modified circular shortest path detection method is applied for refining pupil and iris boundaries using given approximate pupil and iris circles. Brightness gradient direction is employed to choose image pixels, which may belong to pupil or iris boundary. Using initial approximate circles allows the method to work in a narrow ring, which contains only single circular contour. Under these conditions the method allows to correctly handle almost all images used for iris recognition tasks and appears to be more precise than human expert in marking the pupil border. The method was tested with public domain iris databases, containing more than 80000 images totally.
