Spring 2011 GRASP Seminar - Zhengyou Zhang, Microsoft Research, "Human Activity Understanding with Depth Sensors"

Abstract: With the launch of Microsoft Kinect sensors for Xbox 360, depth cameras are becoming affordable for the vision and robotics communities because the mass game market drives the cost down. This could present a revolution in our research. Previously very difficult vision tasks with video cameras become easier, such as foreground-background separation. However, there still exist many challenges. In this talk, I will present some research projects conducted at Microsoft Research, related to human activity understanding with depth sensors. In particular, I will describe a person tracking algorithm based on decision forests and a human action recognition algorithm based on action graph.

Presenter's biography

Zhengyou Zhang is a Principal Researcher with Microsoft Research, Redmond, WA, USA, and manages the multimodal collaboration research team. Before joining Microsoft Research in March 1998, he was with INRIA (French National Institute for Research in Computer Science and Control), France, for 11 years and was a Senior Research Scientist from 1991. In 1996-1997, he spent a one-year sabbatical as an Invited Researcher with the Advanced Telecommunications Research Institute International (ATR), Kyoto, Japan. He has published over 200 papers in refereed international journals and conferences, and has coauthored the following books: 3-D Dynamic Scene Analysis: A Stereo Based Approach (Springer-Verlag, 1992); Epipolar Geometry in Stereo, Motion and Object Recognition (Kluwer, 1996); Computer Vision (Chinese Academy of Sciences, 1998, 2003, in Chinese); Face Detection and Adaptation (Morgan and Claypool, 2010), and Face Geometry and Appearance Modeling (Cambridge University Press, 2011). He has given a number of keynotes in international conferences.

Dr. Zhang is a Fellow of the Institute of Electrical and Electronic Engineers (IEEE), the Founding Editor-in-Chief of the IEEE Transactions on Autonomous Mental Development, an Associate Editor of the International Journal of Computer Vision, and an Associate Editor of Machine Vision and Applications. He served as Associate Editor of the IEEE Transactions on Pattern Analysis and Machine Intelligence from 2000 to 2004, an Associate Editor of the IEEE Transactions on Multimedia from 2004 to 2009, among others. He has been chairs or members of the program committees for numerous international conferences in the areas of autonomous mental development, computer vision, signal processing, multimedia, and human-computer interaction.
