David Zhang graduated in Computer Science from Peking University. He received his MSc in Computer Science in 1982 and his PhD in 1985 from the Harbin Institute of Technology (HIT). From 1986 to 1988 he was 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. Currently, he is a Chair Professor in Department of Computing, at the Hong Kong Polytechnic University where he is the Founding Director of the Biometrics Technology Centre (UGC/CRC) supported by the Hong Kong SAR Government in 1998. He also serves as Visiting Chair Professor in Tsinghua University, and Adjunct Professor in Shanghai Jiao Tong University, Peking University, Harbin Institute of Technology, and the University of Waterloo. He is the Founder and Editor-in-Chief, International Journal of Image and Graphics (IJIG); Book Editor, Springer International Series on Biometrics (KISB); Organizer, the first International Conference on Biometrics Authentication (ICBA); Associate Editor of more than ten international journals including IEEE Transactions and Pattern Recognition; Technical Committee Chair of IEEE CIS and the author of more than 10 books and 200 journal papers. Professor Zhang is a Croucher Senior Research Fellow, Distinguished Speaker of the IEEE Computer Society, and a Fellow of both IEEE and IAPR.

 

Palmprint Authentication
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.
