Unconstrained NIR Spectrum Contact Lens Iris Database (UnMIPA)

The WVU Unconstrained Multi-sensor Iris Presentation Attack (UnMIPA) database consists of 18,706 iris images from 81 subjects. It contains textured contact lenses of blue, green, gray, violet, and brown colors from the following brands: Bausch and Lomb, Freshlook Dailies, Freshlook Colorblends, and Celebration. For each subject, iris images are acquired using 3 iris scanners: CMITECH EMX-30, IriShield BK 2121U, and IriShield MK 2120U.

For each subject in the database, iris images have been captured using different cameras with and without textured contact lens in both indoors (controlled) and outdoors (unconstrained) environment. The iris images acquired outdoor have been acquired at different times of the day as well as in different weather conditions.

    The database can be downloaded from the following link:
