Iris localization, nonlinear normalization, occlusion segmentation, liveness detection, large-scale identification and many other research issues all vasia further investigation. The file naming rules of all three subsets are listed as follows: Because of this novel design, our iris camera can capture very clear iris images see Fig.
The database is released for research and educational purposes.
A copy of all reports and papers that are for public or general release that use the CASIA-IrisV3 should be forwarded upon release or publication to:. The most compelling feature of our dattabase camera is that we have designed a circular NIR LED array, with suitable luminous flux for iris imaging.

Some statistics and features of each subset are summarized in Table 1. Elastic deformation of csaia texture Fig. With fast development of iris image acquisition technology, iris recognition is expected to become a fundamental component of modern society, with wide application areas in national ID card, banking, e-commerce, welfare distribution, biometric passport, and forensics, etc.
Databwse Sun at Dr. Any person or organization is not permitted to distribute, publish, copy, or disseminate this database. All iris images are 8 bit gray-level JPEG files, collected under near infrared illumination.
However, performance of iris recognition systems in unconstrained environments is still far from perfect. Box Beijing China or send electronic copies to znsun nlpr. Questions regarding this database can be addressed to Dr. A copy of all reports and papers that are for public or general release that use the CASIA-IrisV3 should be forwarded upon release or publication to: Although iris is usually regarded as a kind of phenotypic biometric characteristics and even twins have their unique iris patterns, it is interesting to study the dissimilarity and similarity between iris images of twins.
Since s, research on iris image processing and analysis has achieved great progress. Box Beijing Datavase.
The success of investigations into such issues often depends on the availability of carefully acsia iris image databases of sufficient size. Such publicly available datasets are however very limited. Box Beijing China Tel: In all documents and papers that report experimental results based on this database, our efforts in constructing the database should be acknowledged as:
