2.5 Algorithms for Iris Recognition
e systems of iris recognition are used to extract the biometric char-
acteristics of the iris (i.e., biometric template of the iris or iris bio-
metric signature) “gabarit” (template) for secure access to confidential
data or private locations. ese systems, like other biometric systems,
consist first in enrolling the gabarit in a database of identification.
en they are used to create the gabarit for each person wishing to
access the system. e required gabarit will be compared with other
gabarits stored in the database to validate access.
e process of recognition by the biometric method of the iris is
composed of six phases: acquisition of the image of the iris, manipu-
lation of the ima ...
