| 摘 要： | 利用随机场自相关模型，对虹膜图像的自相关特性进行了深入的研究，把环状虹膜展开为矩形表示，以方便虹膜图像的自相关运算，然后，运用3种辨识方法，对简化的自相关模型进行了研究，实验结果表明，理论自相关序列能够较好地与实际自相关序列符合，这对虹膜图像匹配具有重要的意义。 |

| Abstract: | The auto-correlation properties of an iris image are investigated in this paper by a kind of auto-correlation model of random field. The iris part with annular shape is first represented as an array of x rows and y columns in order to make it ease to compute the auto-correlation values of an iris image. The simplified auto-correlation models are studied by three identification methods. Experiment results show that the theory auto-correlation sequences can fit the auto-correlation sequences very well. It means that the auto-correlation model can be used for model match of iris images. |
