摘要
为了实现对虹膜身份识别系统中所采集的序列虹膜图像的质量评判 ,提出了一种利用眼睛结构中瞳孔、虹膜、巩膜各区域边界部分灰度差值评判因子进行质量评价的方法。实验证明 ,用该方法可以快速、有效地鉴定序列虹膜和应变图像的质量 。
An image quality evaluation method by using the gray scale difference factor among the pupil, iris, and sclera boundary is presented in order to realize the quality evaluation of serial iris images that captured by the iris recognition system. The experiment results showed that this method owns the merit of fast and effective on evaluation of serial iris images quality and can improve the efficiency of the iris recognition and experiment mechanics online systems.
