An Accurate and Efficient User Authentication Mechanism on Smart Glasses Based on Iris Recognition

Algorithm 1

The procedure of MIGREP.

Generate a few emitting rays that go from iris region to

  sclera region with fine-tuned parameter set .

For each emitting ray locate the position that exhibits

  the maximal value of the intensity gradient. These

  positions correspond to the hypothesis of the

  boundary point set.

Given the hypothesis of the boundary point set fit a

  parameterized shape (circle or ellipse) to recover the

  outer boundary of an iris.
