Sparsity-based Iris Classification using Iris Fiber Structures

Nalla Pattabhi Ramaiah Nalla Srilatha C. Krishna Mohan
Abstract: As there is a growing demand for biometrics usage in e-Society, the biometric recognition system faces the scalability issue as the number of people to be enrolled into the system runs into billions. In this paper, we propose an approach for iris classification using three different iris classes based on iris fiber structures, namely, stream, flower, jewel and shaker for faster retrieval of identities in large scale biometric system. A sparsity based on- line dictionary learning (ODL) algorithm is used in the proposed classification approach ...
