几种虹膜定位方法的比较

Iris recognition is an emerging biometric technology for personal identification, whereas iris localization is an important part in the process of iris recognition, so obtaining the iris localization precisely and speedy is the prelude. In this paper we put forward two iris localization algorithms based on iris’s circle concourse and gray scale distribution while introducing some prevailing algorithms for iris localization. the two algorithms are simple and easy to realize. Experiments show that the two algorithms are efficient and successful.
