Definition of 'Iris'The most anterior portion of the uveal layer, separating the anterior chamber from the posterior. It consists of two layers - the stroma and the pigmented epithelium. Color of the iris depends on the amount of melanin in the stroma on reflection from the pigmented epithelium. Common names: Iris |
An effective approach for iris recognition using phase-based image matching.
29 Sep 2008 
This paper presents an efficient algorithm for iris recognition using phase-based image matching--an image matching technique using phase components in 2D Discrete Fourier Transforms (DFTs) of given images. Experimental evaluation using CASIA iris ... Read more...
A new method for generating an invariant iris private key based on the fuzzy vault system.
29 Sep 2008 Cryptographic systems have been widely used in many information security applications. One main challenge that these systems have faced has been how to protect private keys from attackers. Recently, biometric cryptosystems have been introduced as a ... Read more...
Increasing the information acquisition volume in iris recognition systems.
8 Sep 2008 A significant hurdle for the widespread adoption of iris recognition in security applications is that the typically small imaging volume for eye placement results in systems that are not user friendly. Separable cubic phase plates at the lens pupil ... Read more...
