Resume of Career

Xiaogang Wang received his Bachelor degree in Electrical Engineering and Information Science from the Special Class of Gifted Young at the University of Science and Technology of China, MPhil. degree in Information Engineering from the Chinese University of Hong Kong, and PhD degree in Computer Science from Massachusetts Institute of Technology. He is an assistant professor in the Department of Electronic Engineering at the Chinese University of Hong Kong since August 2009. He was the Area Chair of IEEE International Conference on Computer Vision (ICCV) 2011. He received the Outstanding Young Researcher in Automatic Human Behaviour Analysis award in 2011, and Hong Kong Early Career Award in 2012.

His research interests include computer vision, pattern recognition, machine learning, and applications to visual surveillance, face recognition, image and video searching, and medical imaging.


Current Research Interests

Crowd behaviour analysis, Object detection and tracking, Person re-identification, Face recognition, Image and video searching, Medical imaging


Highlights of Recent Research Achievements

  • Prof. Wang's group is among the first to start research on vision-based crowd behaviour analysis. At 2007, Prof. Wang published the first nonparametric hierarchical Bayesian model to automatically learn crowd behavior models from local motions without detecting or tracking objects and without supervision. At CVPR 2012, Prof. Wang's group proposed the first agent-based model to learn collective dynamics, and model crowd behaviours at both macroscopic and microscopic levels. At CVPR 2013, Prof. Wang's group published the first work on measuring the collectiveness of crowds from video sequences, which has wide applications to video surveillance, crowd management and crowd video retrieval.
  • Occlusion is a severe problem in crowd video surveillance. Prof. Wang's group proposed hierarchical deep models, and single-pedestrian detection aided by multi-pedestrian detection for occlusion handling. They have achieved the highest pedestrian detection accuracy on three major public benchmark datasets: Caltech, ETH and TUD-Brussels.
  • Prof. Wang's group proposed the first transfer learning framework of automatically transferring a generic pedestrian detector to a scene specific detector without manually labeling any training samples from the target scene. It largely improves the detection accuracy by more than 40% on multiple benchmark datasets.
  • Prof. Wang received three GRF/ECS after joining CUHK for three years. The total amount of research grants secured by this group exceeds 5 million Hong Kong dollars.
  • Prof. Wang received the Hong Kong Early Career Award 2012. There are 19 awardees out of 300 applicants in Hong Kong. CUHK has 6 awardees.
  • Prof. Wang's research works have more than 2000 citations in Google Scholar with an h-index of 21. His profile at Google Scholar can be found at http://scholar.google.com/citations?user=-B5JgjsAAAAJ&hl=en
