The Hong Kong Polytechnic University 3D Fingerprint Images Database Version 2.0

Descriptions

Currently there is no publicly available 3D fingerprint database which is acquired using colored illumination. Therefore a new two-session 2D/3D fingerprints database acquiring from 300 different clients consisting of 2760 different 3D fingerprints is developed. This database has been reconstructed from 5520 colored 2D fingerprints images and is being made available publicly to promote further research efforts in this area. As detailed in the reference, database was acquired during September 2014 to February 2016 in our university and uses 16560 2D fingerprint images to reconstruct entire 3D fingerprint database.

The Hong Kong Polytechnic University Contactless Hand Dorsal Images Database

Descriptions

The Hong Kong Polytechnic University Contactless Hand Dorsal Images Database is contributed from the male and female volunteers. This database has been largely acquired in IIT Delhi Campus, in The Hong Kong Polytechnic University campus and in some villages in India during 2006-2015, mostly by using a mobile and hand held camera. This database has 2505 hand dorsal images from the right hand of 501 different subjects that illustrate three knuckle patterns in each of the four fingers from the individual subject. All the images are in bitmap (*.bmp) format. This database also has additional hand dorsal images from 211 different subjects but these images lack clarity or does not have second minor knuckle patterns. The combined database from 712 different subjects hand dorsal images is made publicly available. This database also provides two session hand dorsal images, with many samples in different age groups that have been acquired after very long interval ( 4 to 8 years) to support studies relating to the stability of knuckle patterns.

The Hong Kong Polytechnic University Cross-Spectral Iris Images Database

Descriptions

This database of iris images has been acquired under simultaneous bi-spectral imaging, from both right and left eyes. This database consists of total 12,540 iris images which are acquired with 15 instances from 209 different subjects. Each of the iris images are of 640 x 480 pixels size and with pixel correspondences in both the near-infrared and visible iris images. Each subject data is stored in separate folder starting from 001 to 209. Each subject's folder consists of two folders, namely VIS and NIR. Again these two folders consists of two more folders for storing left and right iris images. Twelve subjects are also participated in second session and their left and right iris images are also available in this database.

The Hong Kong Polytechnic University 3D Fingerprint Images Databases

Descriptions

The Hong Kong Polytechnic University 3D Fingerprint Images Databases collected from 260 clients, six images per clients, and the entire database of 1560 3D fingerprint images is being made available publicly to promote further research efforts in this area. The database was acquired during February 2012 to May 2012 in our university and uses 10920 2D fingerprint images to reconstruct entire 3D fingerprint database.

The Hong Kong Polytechnic University Disguise and Makeup Faces Database

Descriptions

This database consists of 2460 different face images from 410 different subjects. These images have been acquired under real environment which primarily focuses on make-up and disguises covariates. This database also provides ground truth (eyeglass, goggle, mustache, and beard) to evaluate capability of advanced algorithms in automatically oredicting them for advanced surveillance capabilities. The people in the database are acquired from the publicly accessible websites. Majority of them are celebrities from the movie, music, sports and also politics. Celebrities from the Europe and US are the majority, along with some from Asia, Africa, Pacific and Middle East. Each person in the database has six images, the first image is selected to represent clean impression. The rest of the five face images are faces with different levels of makeup or disguise creating accessories.

The Hong Kong Polytechnic University Contactless Finger Knuckle Images Database (Version 1.0)

Descriptions

The Hong Kong Polytechnic University contactless finger knuckle images database (Version 1.0) is contributed from the male and female volunteers. This database has been largely acquired in The Hong Kong Polytechnic University campus and IIT Delhi Campus during 2006-2013 using a contactless setup that simply uses a hand held camera. This database has 2515 finger dorsal images from the middle finger of 503 subjects, all the images are in bitmap (*.bmp) format. In this dataset about 88% of the subjects are younger than 30 years old.

The Hong Kong Polytechnic University Contact-free 3D/2D Hand Images Database (Ver 1.0)

Descriptions

The 3D hand images in the database were acquired using a commercially available 3D digitizer Minolta VIVID 910. The data collection process spanned over 4 months and 177 subjects volunteered for the database. The participants were mainly the students and staff from our institute and were in the age range of 18 ~ 50 years, with multiple ethnic backgrounds. Each subject contributed 5 hand images (range and a registered intensity image acquired simultaneously) in the first session, followed by another 5 in the second session. Therefore our database currently has 3,540 hand images (of 3D and corresponding 2D). Time lapse between two data collection sessions was not fixed for all subjects; instead it ranged from a minimum of one week (only for 27 subjects) to three months. All the hand images were collected in indoor environment, with no restrictions on the surrounding illumination. In fact, our data collection process was carried out at three different locations which had notable variations in surrounding illuminations.

The Hong Kong Polytechnic University Contact‐free 3D/2D Hand Images Database (Version 2.0)

Descriptions

The 3D hand images in the database were acquired using a commercially available 3D digitizer Minolta VIVID 910. The database acquisition was performed in our university. The volunteers were the student, staff of our university and also included visitors from elsewhere. This database currently contains 1140 right hand images (3D and the corresponding 2D) acquired from 114 subjects. In order to introduce considerable pose variations in the database, subjects were instructed to present their hand in five different poses.
