Iris Recognition Research Package for Non-Ideal Iris Conditions

This package contains research code accompanying a paper on non-ideal iris recognition systems, including systematic study tools and a small sample image collection (20 users). The implementation features batch processing capabilities for iris image analysis and supports angle-variant iris capture scenarios (0°, 15°, 30° frontal views). Researchers needing full access to West Virginia University's non-ideal iris database should contact the specified researchers for complete dataset acquisition.
