The
Multispectral Palmprint Database
Overview:
Palmprint is a unique and reliable biometric
characteristic with high usability. With the increasing demand of highly
accurate and robust palmprint authentication system,
multispectral imaging has been employed to acquire more discriminative
information and increase the antispoof capability of palmprint.
The Biometric Research Centre
(UGC/CRC) at The Hong Kong Polytechnic University has developed a real time
multispectral palmprint capture device which can
capture palmprint images under blue, green, red and
near-infrared (NIR) illuminations, and has used it to construct a large-scale
multispectral palmprint database. To advance research
and to provide researchers working in the area of multispectral recognition
with a platform to compare the effectiveness of various multispectral palmprint recognition algorithms, we intend to publish our
multispectral palmprint database, making it freely
available for academic, noncommercial uses.
The outlook of the multispectral palmprint image acquisition device.
Description of the PolyU multispectral palmprint Database:
Multispectral palmprint images were collected from 250 volunteers,
including 195 males and 55 females. The age distribution is from 20 to 60 years
old. We collected samples in two separate sessions. In each session, the
subject was asked to provide 6 images for each palm. Therefore, 24 images of
each illumination from 2 palms were collected from each subject. In total, the
database contains 6,000 images from 500 different palms for one illumination.
The average time interval between the first and the second sessions was about 9
days.
Each folder is named as “nnnn”. “nnnn”
represents the identity of the person (range from 1 to 500). In each folder,
the first 6 images (1_mm) were captured in the first session and the latter 6
images (2_mm) were captured in the second session, "mm" represents
the image index for give session (range from 1 to 6). “Blue.rar”,
"Green.rar", "Red.rar" and "NIR.rar" contains all
the original palmprint images collected with our
device by blue, green, red and NIR illumination. We also provide the extracted
ROI images using our ROI extraction algorithm described in [1]. ROI images are
contained in “ROI Database.rar”.
