Completely Contactless Finger Knuckle Detection and Identification for Real World Applications
By Ajay Kumar, The University of Hong Kong, Hong Kong.
Abstract:
Finger knuckle patterns are highly unique and correlated with the anatomy of fingers that involve a complex interaction of finger phalanx bones, tissues, and interphalangeal joints. Such patterns are increasingly employed for forensic identification, by the FBI and other law enforcement departments in the world, especially when knuckle patterns are only the piece of available evidence to identify the suspects. Unrelenting hygienic concerns to stop the spread of COVID19 and the wide availability of smartphones have attracted renewed attention to developing completely contactless finger knuckle identification capabilities. During this talk, our discussion will focus to uncover enormous potential from various finger knuckle patterns for completely contactless and online personal identification. We will also discuss the stability of knuckle patterns, from a database acquired at several years of intervals, among individuals from different age groups. The effectiveness of knuckle minutiae and other feature extraction algorithms will also be analyzed. Experimental results from contactless finger knuckle databases, including those from over 700 different subjects, will also be presented. During this talk, I will also present a live demonstration of the world’s first completely contactless and online finger-knuckle identification system which has been developed at PolyU.
