GIRIST (GRUS IRIS TOOL) is a free iris recognition software by GRUSOFT. The performance of Girist is comparable to the best commercial systems.It’s based on the novel Giris SDK.

Some Key Features of GIRIST

  1.        Average Decidability > 6.0
  2.        Average Correct Recognition Rate >95%
  3.        When FAR=0.01%, average FRR=5%
  4.        Average Extraction time <0.4s
  5.        Match rate>50000 irises/second
  6.        Handle noises such as eyelash, eyelids and strong reflections
  7.        Upper limit of Rotation Angle:  ±15 degrees
  8.        No limits on size of iris.
  9.        Unlimited database size
  10.        Three mode: iris authentication, iris identification and iris library verification
  11.        Interactive graphical user interface(Figure 1 )

The performance of GIRIST has been verified by the datasets of CASIA, UBIRIS and MMU IRIS. And the testing CPU is Intel Core 2.0 GHz.

Experimental Results 

The performance of the GIRIST was tested on 6 datasets, 3 of CASIA, 2 of UBIRIS and MMU. Table 1 lists the detail of these datasets. Table 2 lists the experimental results. As you see, GIRIST is fast and stable. GIRIST can handle noises such as eyelash, eyelids and strong reflections(Figure 2).
