| Abstract(in English) | An iris recognition system that employs a rotation spreading neural network (R-SAN net) can recognize the rotation angle of the input iris pattern. The change in the rotation of iris pattern is corrected by using the recognized rotation angle obtained by R-SAN net. In this study, we evaluated the suitable criterion of the rotation correction and the -orientation recognition performance. The rotation change within 10 degrees had no effect on the iris recognition performance with the spread pattern generated by R-SAN net. This result showed that the orientation correction was required to prevent the decrease of the iris recognition performance when the rotation change of input iris pattern was over 10 degrees. On the other hand, the orientation recognition experiments showed that the decrease of the rotation recognition performance was caused by the slight errors of iris and pupil detections. |
