A personal identification system based on iris recognition
Xue Bai · Guangdian gongcheng · 2004
A personal identification system based on iris recognition consists of three parts: iris image sampling, iris image preprocessing, iris image coding and recognition. Precision locating for iris in the process of preprocessing makes iris image have invariance in translation, size and rotation. Compared with the existing methods, the method applies Symplets wavelet to iris image coding and the operation speed of this algorithm is largely improved. The speed is 8 times of that of Daugman method and it solves the problem of too large calculation amount existed in the current algorithms.
