| 摘要: |
| 通过普通摄像头得到的虹膜图像的纹理通常是模糊的,不能直接用于虹膜识别,先对虹膜图像获取、内外边缘定位,然后采用基于B样条的FFD模型对图像进行配准,采用小波变换对图像进行融合,然后对图像进行二值化和特征提取处理,对虹膜识别中的算法进行改进,提出了一种嵌入式虹膜识别算法,对该算法的实验表明,算法运算速度快$精度高$性能稳定,适合在嵌入式系统中应用. |

| Abstract: |
| The texture of iris images taken by an ordinary camera are usually blurred and can not be directly used for iris recognition.Firstly,iris images are taken and inside and outside edges are positioned,then FED Model based on B-spling is used to register the |
