Yong Xu

Yong Xu was born in Sichuan (China, 1972). He received his BS degree and MS degree at Air Force Institute of Meteorology (China, 1994 and 1997, respectively). He then received his PhD degree in pattern recognition and intelligence system at the Nanjing University of Science and Technology (NUST) in 2005. From May 2005 to April 2007, he worked at Shenzhen graduate school, Harbin Institute of Technology (HIT) as a postdoctoral research fellow. Now he is an associate professor at Shenzhen graduate school, HIT. He also acts as a research assistant researcher at the Hong Kong Polytechnic University from August 2007 to June 2008. He has published more than 40 scientific papers. He is an associate editor of the International Journal of Image and Graphics, a reviewer of several international journals such as IEEE Transactions on Systems, Man, and Cybernetics, International Journal of Pattern Recognition and Artificial Intelligence and Neurocomputing. His current interests include pattern recognition, biometrics, machine learning, and image processing.
