Abstract

Iris location is one of key steps in iris recognition system. Utilizing erosion operator, the inner-edge of iris was located. We reconstructed the 3D surface of eyeball by viscosity solution of Eikonal equation in shape from shading. According to the change rate between iris and sclera on the 3D surface, outer-edge of iris was picked up. For eyelids, a statistical parabolic template was proposed to locate them. Experiment results show that the algorithm can give quick and precise iris location and has good robustness
