Iris localization is one important stage in iris recognition system. The goal of iris localization is to find the boundary between iris and sclera and between iris and pupil. Because the shape of pupil and the shape of iris look very close to a circle, most of the iris localization algorithm tries to perform circle fitting on the eye image. In this way, the results of iris localization can be expressed as two circles.
