Department of Computer Science Colloquium
2010 Series

Free Hand Interaction from Stereo Camera

Prof. Xilin Chen
Institute of Computing Technology
Chinese Academy of Sciences

Date: December 14, 2010 (Tuesday)
Time: 10:30 - 11:30 am
Venue: SCT716, Cha Chi Ming Science Tower, Ho Sin Hang Campus

In recent year, HCI attracts more and more attention in both academics and industry. As one of the most natural HCI modality, gesture has been widely used in touch based interaction. However, 2-D based hand gesture is not enough for more complicated cases. Free hand interaction can provide 3-D manipulation capability. In this talk, we will focus on free hand detection and tracking. A human-dependent color model is learned from detected face, and rough hand regions are cropped based on the color model. Stereo camera provides fine segmented hand and depth information for further classification. The potential application includes remote controller, game interaction, and etc.

Dr. Xilin Chen received the BS, MS, and PhD degrees in computer science from Harbin Institute of Technology, China, in 1988, 1991, and 1994, respectively. He was a professor at Harbin Institute of Technology from 1999 to 2005. He was a visiting scholar at Carnegie Mellon University, Pittsburgh, Pennsylvania, from 2001 to 2004. He has been a professor at the Institute of Computing Technology, Chinese Academy of Sciences (CAS), Beijing, since August, 2004. He is now the director of the Key Laboratory of Intelligent Information Processing, CAS. He has published one book and more than 200 papers in refereed journals and conference proceedings in the areas of computer vision, pattern recognition, image processing, and multimodal interfaces. He is an associate editor of the IEEE Transactions on Image Processing, an area editor of the Journal of Computer Science and Technology, and an associate editor of the Chinese Journal of Computer. He was the program chair of ICMI 2010, and he is the tutorial chair of FG 2011. He has served as a program committee member for more than 30 international conferences. He has received several awards, including the China’s State Scientific and Technological Progress Award in 2000, 2003, and 2005 for his research work. He is a senior member of the IEEE and also a member of the IEEE Computer Society.

The talk is partially supported by the Croucher Foundation.
