摘要
为了克服传统Hough变换在虹膜定位应用中计算速度慢,需要存储空间大的缺点,把改进的Hough变换和Canny边缘检测结合,提出一种新的虹膜定位快速算法。实验证明,算法较传统Hough变换在虹膜定位应用中具有更快的速度,并且需要更小的存储空间。
In order to overcome the weakness of Hough transformation when applied in iris location,a new fast iris location algorithm was proposed,which combined modified Hough transformation and Canny operator.The result of experiment vadicats that,the algorithm proposed was more fast and more space saving than the traditional Hough transformation.
