| 摘 要： | 为了能快捷方便地从眼部图像中分割虹膜图像,本文将原用于模拟脑部主要直观皮层中复杂细胞的Gabor能量算子用作眼部图像的滤波函数.实验表明,通过对该Gabor能量函数非CRF抑制、相关参数的分析和优化,该方法能较好地将瞳孔纹理从眼部图像分离,从而方便地实现虹膜提取,并能简化虹膜识别系统的程序、提高其处理速度.

| Abstract: | In order to segment the iris patterns from an eye picture quickly and conveniently,this paper treats the Gabor energy operator which was formerly used to simulate the complex cells in primary visual cortex as an eye picture filter function.Through non-CRF inhibiting,and analyzing and optimizing related function parameters,the experiment indicates that this method can distinguish the pupil texture from an eye picture much better,thus can implement the iris texture extraction conveniently,simplify the procedure of the iris recognition system,and improve its processing speed. |
