Low resolution iris image can degrade the performance of iris recognition. A new iris image zooming method by using edge-directed image upsampling method based on radial basis function (RBF) interpolation [9] is proposed to restore a single iris image into a highresolution image. By increasing the resolution of iris image, we found that the performance of iris recognition was increased.

In recent years many authors have recognized that the path forward, regarding iris recognition, is the development of iris recognition systems that can work independently of the conditions under which iris images are acquired. Recent works have tried to achieve robust and unconstrained iris recognition in order to develop real-world applicable methods. In this work, the problem of unconstrained...

Iris based authentication system is a pattern recognition technique that makes the use of iris patterns, which are statistically unique. The richness and apparent stability of the iris texture make it a robust biometric trait for personal authentication. Iris is a unique part which does not change with respect to time and also every individual has unique and different pattern of iris for both t...

Iris recognition used the iris features to verify and identify identity of human. The has many advantages such as stability over time, easy use high accuracy. However, poor quality images can degrade accuracy system. this system is depended on pattern captured during acquisition. due blurry image. Blurry image happened movement acquisition camera resolution. Due that, a deblurring method based ...

Problem statement: The study presented an efficient Iris recognition system. Approach: The design used the discrete cosine transform for feature extraction and artificial neural networks for classification. The iris images used in this system were obtained from the CASIA database. Results: A robust system for iris recognition was developed. Conclusion: An iris recognition system that produces v...

The demand for an accurate biometric system that provides reliable identification and verification of an individual has increased over the years. A biometric system that provides reliable and accurate identification of an individual is an iris recognition system. Iris recognition systems capture an image of an individual's eye; the iris in the image is then segmented and normalized for feature ...
