I joined Visual Computing Group, Microsoft Research Asia in Sept. 2006. Before that, I obtained my Ph.D degree in 2006 under the supervise of Prof. Long Quan in Department of Computer Science and Technology, The Hong Kong University of Science and Technology, and B.S.E degree in Peking University in 2001.


  • Experiment results and ground truth mask for ECCV 2012 saliency paper (an error in the precision/recall number has been corrected, please use the latest result)
