بصمة العين
Iris recognition biometric systems apply mathematical pattern-recognition techniques to images of the irises of an individual's eyes.
Iris recognition system based on pattern matching
بصمة العين Iris recognition، هي طريقة آلية للقياس الحيوي باستخدام تقنيات التعهد ذات النمط الرياضي الخاصة حيث يتم عمل تصوير ڤيديولقزحية العين، والتي تتميز أنماطها العشوائية المعقدة بأنها متميزة ويمكن رؤيتها من على بعد.
التاريخ
طول الموجة المرئي لقاء التصوير بالأشعة الحمراء
| Visible Wavelength Iris Image | Near Infrared (NIR) version |
|---|---|
Visible light reveals rich pigmentation details of an Iris by exciting Melanin, the main colouring component in the iris.
|
Pigmentation of the Iris is much less visible due to the negligible effects of Melanin at longer wavelengths in the NIR spectrum
