一种虹膜图像综合质量评价方法

An Integrated quality evaluation approach of iris image

在虹膜识别系统中,虹膜图像的质量是影响识别效果的一个重要因素,在对现有虹膜图像质量评价算法分析的基础上,针对引起"注册失败"的最主要的几个因素,建立了一种综合的虹膜质量评价模块。实验表明,该方法的虹膜质量综合评价因子对虹膜图像的质量评价结果符合主观评价方法的评价结果。

In the iris recognition system, the quality of iris image is important factor to affect the recognition rate, on the base of iris image quality evaluation module in existence, a integrated iris image quality evaluation is proposed by considering the main factors which may cause failure. Experimental results show that the approach can be consistent with the subjective experience approach on image quality.
