The
2D_3D_Palmprint Database
Overview:
Palmprint has proved to be
one of the most unique and stable biometric characteristics. Almost all the
current palmprint recognition techniques capture the two dimensional (2D) image
of the palm surface and use it for feature extraction and matching. Although 2D
palmprint recognition can achieve high accuracy, the 2D palmprint images are
relatively easy to be counterfeited and much three dimensional (3D) depth
information is lost in the imaging process. 3D Palmprint is a good choice to
overcome these flaws.
The Biometric Research Centre
(UGC/CRC) at The Hong Kong Polytechnic University has developed a real time 3D
palmprint capture device, and has used it to construct a large-scale 3D
palmprint database. To advance research and to provide researchers working in
the area of 3D palmprint recognition a platform to compare the effectiveness of
3D palmprint recognition algorithms, we intend to publish our 3D palmprint
database, making it freely available for academic, noncommercial uses.

Description of the PolyU 3D Palmprint Database:
The PolyU 3D Palmprint
Database contains 8000 samples collected from 400 different palms. Twenty
samples from each of these palms were collected in two separated sessions,
where 10 samples were captured in each session, respectively. The average time
interval between the two sessions is one month. Each sample contains a 3D ROI
(region of interest) and its corresponding 2D ROI. Each 3D ROI is recorded by a
binary file which contains 128*128 float values denoting the depth infromation
of the palmprint to a reference plane, where each 2D ROI is recorded by a BMP
format image file. The 3D ROIs are stored in the folder, "Sub3D", and
labeled as "Sub3D_I_M_N.dat" or "Sub3D_II_M_N.dat", where
"I" indicates the first session, "II" indicates the second
session, "M" is the unique palm identifier (range from 1 to 550, some
numbers are absent), and "N" is the index of each palm (range from 0
to 9). The 2D ROIs are stored in the folder "Sub2D", and labeled as
"Sub2D_I_M_N.bmp" or "Sub2D_II_M_N.bmp" which are
one-to-one corresponding to their 3D ROIs.
