Abstract:

In recent times, an increasing, worldwide

effort has been devoted to the development of automatic

personal identification systems that can be effective

in a wide variety of security contexts. As one of the

most powerful and reliable means of personal authentication,

biometrics has been an area of particular interest.

This interest has led to the extensive study of biometric

technologies such as fingerprint and face recognition

and the development of numerous algorithms, applications,

and systems. Palmprints, in particular, have attracted

a lot of interest. Recent interest in palmprints is

justified. Palmprints have a number of unique advantages:

they are rich in features such as principal lines, wrinkles,

and textures and these provide stable and distinctive

information sufficient for separating an individual

from a large population. Having worked on palmprints

since 1996, our team certainly regards the palmprint

as a very effective biometric. In this presentation,

we would like to provide a comprehensive introduction

to palmprint technologies. It reveals automatic techniques

for palmprint authentication, from the first approach

based on offline palmprint images, to the current state-of-the-art

algorithm using online palmprint images. We will discuss

various algorithm design methodologies, and architectures,

as well as at the different stages of implementation

of a palmprint system including palmprint segmentation,

feature extraction, matching, and classification. Also,

a palmprint acquisition device and a palmprint identification

system prototype are given. To encourage more people

to join us in our research into palmprint technology,

we have made available part of our palmprint database

for the public to download. Further details can be found

Bio of the Speaker:

David Zhang graduated in Computer Science

from Peking University in 1974. In 1983 he received

his MSc in Computer Science and Engineering from the

Harbin Institute of Technology (HIT) and then in 1985

his PhD from the same institution. From 1986 to 1988

he was first a Postdoctoral Fellow at Tsinghua University

and then an Associate Professor at the Academia Sinica,

Beijing. In 1994 he received his second PhD in Electrical

and Computer Engineering from the University of Waterloo,

Ontario, Canada. Professor Zhang is currently at the

Hong Kong Polytechnic University where he is the Founding

Director of the Biometrics Technology Centre (UGC/CRC)

(www4.comp.polyu.edu.hk/~biometrics/) a body supported

by the Hong Kong SAR Government. He also serves as Adjunct

Professor in Tsinghua University, Shanghai Jiao Tong

University, Harbin Institute of Technology, and the

University of Waterloo. Professor Zhang's research interests

include automated biometrics-based authentication, pattern

recognition, and biometric technology and systems. He

is the Founder and Editor-in-Chief, International Journal

of Image and Graphics (IJIG) (www.worldscinet.com/ijig/ijig.shtml);

Book Editor, Kluwer International Series on Biometrics

(KISB) (www.wkap.nl/prod/s/KISB); and Program Chair,

the First International Conference on Biometrics Authentication

(ICBA), Associate Editor of more than ten international

journals including IEEE Trans on SMC-A/SMC-C, Pattern

Recognition, and is the author of more than 130 journal

papers, and 35 books/book chapters. As a principal investigator,

Professor Zhang's has since 1980 brought to fruition

many biometrics projects and won numerous prizes. In

1984 his Fingerprint Recognition System won the National

Scientific Council of China's third prize and in 1986

his Real-Time Remote Sensing System took the Council's

first prize. In 2002 his Palmprint Identification System

won a Silver Medal at the Seoul International Invention

Fair, following that in 2003 by taking a Special Gold

Award, a Gold Medal, and a Hong Kong Industry Award.

Professor Zhang holds a number of patents in both the

USA and China and is a current Croucher Senior Research

Fellow.
