3D Finger Knuckle Images Database
The final version 3D finger knuckle database has been acquired from 228 different subjects and among these 190 subjects have volunteered to provide second session's data. Each of these subjects provided six forefinger 3D knuckle images and six middle finger 3D knuckle images.

Contactless Finger Knuckle Images Database (Version 3.0)
This database has 1950 finger knuckle images from the index finger of 221 subjects, all the images are in .JPG format. This database also provides two session finger knuckle images acquired after very long interval (4 to 7 years) to ascertain stability of knuckle crease and curved lines. Besides, this database also includes segmented finger knuckle images, contrast-enhanced images and center point information of every finger knuckle images used for segmentation to extract a normalized region.

Finger Knuckle Database (Version 1.0)
The currently available database is from 158 users, all the images are in bitmap (*.bmp) format. All the subjects in the database are in the age group 16-55 years. This database of 790 images have been sequentially numbered for every user with an integer identification/number. The resolution of these images is 80 ´ 100 pixels and all these images are available in bitmap format.
