A new approach for iris localization in iris recognition systems
2008 IEEE/ACS International Conference on Computer Systems and Applications, 2008This paper presents a new approach for iris localization which consists of one of the most important steps in an iris recognition system. We have solved some of the most important drawbacks of the current methods using a pointwise level set algorithm, which detects the precise location of the iris by a stepwise deformation of an initial contour. Due to

Improved iris localization method for iris recognition
Sixth International Conference on Optical and Photonic Engineering (icOPEN 2018), 2018Iris recognition technology has advantages of high security and high stability and can realize non-contact and living recognition. For iris recognition, iris localization is the first step. The localization precision is assurance of high recognition rate. The existing iris localization method has shortage of slow speed.

Real-Time Iris Localization for Iris Recognition in Cellular Phone
Sixth International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing and First ACIS International Workshop on Self-Assembling Wireless Networks (SNPD/SAWN'05), 2005With the increasing need of guaranteeing the security in case of using bank transaction service by using cellular phone, it is required to apply biometrics for the security of cellular phone. Especially, iris recognition is good for cellular phone security because of its reliability and accuracy compared to other biometrics such as face, fingerprint ...

Application of evolutionary algorithms for iris localization
2009 IEEE International Conference on Multimedia and Expo, 2009An iris recognition system requires efficient image processing techniques in order to duly represent and interpret the iris structural characteristics of an individual. The first processing stage should be the identification of the iris region in an eye image.

Localized Benign Lymphoid Tumor of the Iris
Archives of Ophthalmology, 1981• A 32-year-old white woman noted a localized light-brown tumor on the iris of her right eye. During the following year, the lesion progressively enlarged and was surgically removed because it was suspected to be an iris melanoma. Histologic study disclosed an unusual benign tumor composed of mature lymphocytes and epithelioid cells.

Novel algorithm for iris localization
SPIE Proceedings, 2007With the emerging security demands, biometric identification technology has attracted more and more attention in recent years, and iris recognition is one of the most reliable biometric technologies. Iris localization is a crucial part in the iris recognition, which is quite time-consuming and easily disturbed by various noises, especially the ...

Iris pattern localization method
2016 15th Workshop on Information Optics (WIO), 2016In this paper, the biometric recognition systems of individuals based on iris recognition is studied, we present a method for locating iris from human eye image, we propose to extract iris edges' by mean of threshold to find the circle of the pupil as first step. The second step is to find the external iris edge using hough transform.

A New Method for Iris Localization
2007 2nd IEEE Conference on Industrial Electronics and Applications, 2007Iris localization is one of the most important steps in iris recognition system and determines the accuracy of matching. In this paper, a new method for iris localization is proposed. Firstly, we adopt edge points detecting to find out the iris' inner boundary.

A Fast Method for Iris Localization
2011 Second International Conference on Emerging Applications of Information Technology, 2011Iris localization is an important step in iris recognition system and performance of the recognition system depends on the accuracy of the localization. In this paper, we have proposed an iris localization method. Here, we identify both outer and inner circular boundary of the iris.
