The NIST IrisDaily Dataset: Description and Initial Analysis



James Matey


This paper describes a dataset, IrisDaily-NIST, that is under construction by NIST. At the present, this dataset has (nearly) daily iris images of a single subject collected with a commercial iris camera over a period of approximately 4 months. The purpose of the dataset is to enable evaluation of long and short term variability in match scores under optimal conditions. We present initial analysis of the data using two commercially available algorithms.
Technical Note (NIST TN) - 2155
Report Number
