PolyU-IITD Contactless Palmprint Images Database (Version 3.0)

There has been significant advances in the palmprint identification technologies in last two decades. The accuracy from the many contact-based public palmprint databases are near 100% and these are no longer relavent to advance research on the development of palmprint image algorithms for contactless personal identification. There are some contactless palmprint databases in public domain which have also began to mature as the accuracy from state of art contactless palmprint matching algorithms is very high. A key limitations of existing contactless palmprint databases is that these are acquired under indoor environmenrts or using well-designed imaging setups while advancement of contactless palmprint technologies in new domains demands capabilities to match palmprint images acquired under ambient illuminations. Lack of representative palmprint images from the deployment scenarios, e.g. palm images with cosmetics like popular mehendi in India, palmprints with injury, dirt, handwritings, or palm images from persons with special abilities or from manual laborers.  Several year of efforts have resulted in the development of such database for the research. The objective has been to establish large scale contactless palmprint image database that is representative of deployment scenarios and the likely users in many popular applications.

Brief Description

This database has been acquired from the volunteers in India and China. This is first such joint database of its kind and acquired at various locations using a general purpose hand-held camera. This new palmprint database has been acquired over several years from (over) 600 different subjects which is largest to-date in the best of our knowledge or at least until August 2020 literature. Each subject in this database has provided his/her left and right hand images. The images in this database therefore also have high scale variations and are acquired from subjects. There are twenty images from each of the subjects whose age ranges from 5 years to 72 years. The subjects are from diverse population group that includes non-officer works, farmers, countryside laborers, injured palms and hands with special capabilities or injuries. This database also have palmprint image samples acquired over fifteen years of interval and forms one of the unique contributions from this database.

Sample Images

The entire database as detailed above is made available for the research. Reference [1] that introduces this database utilzed 'first' 600 subjects palm images as per the stated protocol and these can be used for performance comparison. The sample images from this database are reproduced in the following image sets.
