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
