Authentication is the process of determining whether someone or something is, in fact, who
or what it is declared to be. As the dependence upon computers and computer networks …

Noncontact biometrics such as face and iris have additional benefits over contact-based
biometrics such as fingerprint and hand geometry. However, three important challenges …

Finger-vein recognition refers to a recent biometric technique which exploits the vein
patterns in the human finger to identify individuals. The advantages of finger vein over …

This paper presents a shift, scale, and rotation-in-variant technique for iris feature-
representation and fused postclassification at the decision-level to improve the accuracy and …

We present algorithms for iris segmentation, feature extraction and selection, and iris pattern
matching. To segment the inner boundary from a nonideal iris image, we apply a level set …

In this paper, we propose a novel possibilistic fuzzy matching strategy with invariant
properties, which can provide a robust and effective matching scheme for two sets of iris …

Segmenting iris texture from an input image is an important step for recognising iris pattern.
It is still a difficult task to localise available texture regions from non-ideal iris images …

In a less constrained capture of iris images to build a high-speed iris recognition system, the
design of a robust and fast iris segmentation method is important. In this paper, a new iris …

Continuous efforts have been made to process degraded iris images for enhancement of the
iris recognition performance in unconstrained situations. Recently, many researchers have …

Besides the iris, conjunctival vasculature may also be used for ocular biometric recognition.
Conjunctival vessel patterns can be easily observed in the visible spectrum and can …
