Iris Recognition

Daugman

Developed an algorithm that could perform iris Recognition

“Father” of iris Recognition

3 parts
  • Segmentation
  • Normalization
  • Encoding

Anatomy

Primary purpose of the iris is to regulate the light that enters the pupil

see magna notebook

Why is iris obtained in near infrared spectrum
  • Cant get textures from dark iris with visible light since melinan absorbs it
  • Iris reacts to visible light, and shrinks or grows, near IR does not affect the iris

Chaomorphagenesis - randomness of iris

Left and right iris are different from each other

Algorithm

How do we extract the iris from the ocular region?
