The Unconstrained Fingerphoto Database (UNFIT database) consists of fingerphotos captured using 45 different smartphones. It has data for 115 subjects, collected for both index and middle finger, separately and together. Hence, there are a total of 230 classes. This database covers many challenges present in a real-world unconstrained environment such as illumination, motion blur, affine variations, and optional usage of the camera flash. The database also includes ground truth annotations of the location of the finger(s).
