• F2 is a set of 72 images taken by the Sony CCD color camera
with a resolution of 520 TV lines.
• F3 is a set of 150 images issued from the CASIA iris image
database (Miyazawa et al. 2005).
For each image belonging to the families Fj, we will determine the
external edge C1 and the internal edge C2 previously defined.
Both edges are considered as a circle in the methods used in simu-
lation 1, simulation 2, simulation 3, and simulation 5. is circle will
