摘要:

提出了一种基于圆形模糊虹膜分割(CFIS)和Gabor解析虹膜纹理二进制编码器(GAITBE)的虹膜识别方法。CFIS过程被设计为保证对于相似的眼睛图像将获得相似的虹膜片段,尽管事实上遮挡程度可能从一个图像到另一个图像而变化。其结果是一个圆形的虹膜环(与瞳孔同心),近似于实际的虹膜。GAITBE证明了利用希尔伯特变换从不同虹膜中提取的虹膜编码之间的统计独立性。来自巴斯大学虹膜数据库的虹膜以两种不同的长度(768 / 192字节)进行二进制编码,并在单次注册和多次注册识别场景中进行测试。所有的情况下说明的能力,新提出的方法,以缩小类间匹配分数的分布,因此,以保证一个陡峭的下降的错误接受率。

英文摘要:

A new approach in iris recognition based on Circular Fuzzy Iris Segmentation (CFIS) and Gabor Analytic Iris Texture Binary Encoder (GAITBE) is proposed and tested here. CFIS procedure is designed to guarantee that similar iris segments will be obtained for similar eye images, despite the fact that the degree of occlusion may vary from one image to another. Its result is a circular iris ring (concentric with the pupil) which approximates the actual iris. GAITBE proves better encoding of statistical independence between the iris codes extracted from different irides using Hilbert Transform. Irides from University of Bath Iris Database are binary encoded on two different lengths (768 / 192 bytes) and tested in both single-enrollment and multi-enrollment identification scenarios. All cases illustrate the capacity of the newly proposed methodology to narrow down the distribution of inter-class matching scores, and consequently, to guarantee a steeper descent of the False Accept Rate.
