Clarkson Longitudinal Iris in Children Database (CLIC) – Matching and Quality Scores

Funded by National Science Foundation (NSF). The database release agreement for Clarkson University can be found by clicking here.  To request the following dataset, please contact and indicate the specific dataset.  Please see link below for additional details of the dataset.

Release Summary

Verification match scores of the dataset along with the metadata (detailed below) would be shared as part of the release.

A longitudinal iris database is created with data from 209 children in the age group of 4 to 11 years at enrollment over a time period of 3 years from 7 sessions. All subjects may/may not have participated in all 7 sessions. The data would not be shared as part of this release to protect the privacy of children. The data would be available in the BEAT platform- , for algorithms testing for research  purpose.  Protecting  the privacy  of  the  data  and  the  individuals,  the  platform  will restrict public access to the data, while giving feedback on the statistics of the performance of the algorithms. Detailed instructions on accessing the dataset for experimentation would be shared here soon.
