This survey covers the historical development and current state of the art in image
understanding for iris biometrics. Most research publications can be categorized as making …

Images of a human iris contain rich texture information useful for identity authentication. A
key and still open issue in iris recognition is how best to represent such textural information …

In this paper, we propose a novel palmprint verification approach based on principal lines. In
feature extraction stage, the modified finite Radon transform is proposed, which can extract …

Iris recognition has become a popular research in recent years. Due to its reliability and
nearly perfect recognition rates, iris recognition is used in high security areas. Among its …

This paper proposes algorithms for iris segmentation, quality enhancement, match score
fusion, and indexing to improve both the accuracy and the speed of iris recognition. A curve …

Template security is a critical issue in biometric systems because biometric templates cannot
be easily revoked and reissued. While multibiometric systems overcome limitations such as …

The randomness of iris pattern makes it one of the most reliable biometric traits. On the other
hand, the complex iris image structure and the various sources of intra-class variations result …

This paper addresses the issue of counterfeit iris detection, which is a liveness detection
problem in biometrics. Fake iris mentioned here refers to iris wearing color contact lens with …

Multibiometric systems are gaining popularity because they are able to overcome limitations
such as non-universality, noisy sensor data and susceptibility to spoof attacks common in …

This paper describes the Iris Challenge Evaluation (ICE) 2005. The ICE 2005 contains a
dataset of 2953 iris images from 132 subjects. The data is organized into two experiments …
