| Abstract(in English) | We have developed a real-time iris recognition system using a rotation spreading neural network. The previous iris recognition system did not accurately detect the pupil and iris edges if the ambient light condition changed, during the acquisition of the iris pattern in sometimes. In the present study, we attempted to improve the detection of the pupil and iris edges by normalizing the surrounding brightness of the eye. In result, the system became to detect the pupil and iris edges accurately even if the ambient light condition changed. Furthemore, the spoofing using photograph of the iris was not avoided in the previous system. We knew the previous system recognized 75% of the iris photograph. In the present study, the recognition rate using the photograph of the iris became 0% by adding the algorithm for the rejection of the counterfeit iris with the iris constriction caused by illuminating the flash light. |
