STUDENT NEWS

Dr. Yang Wang successfully defended his Ph.D. thesis Learning Structured Models For Human Actions And Poses. Congratulations Yang!
Weilong Yang (MSc) and Yang Wang (PhD) had papers on transfer learning for human action recognition accepted to the Asian Conference on Computer Vision (ACCV) and 2nd International Workshop on Machine Learning for Vision-based Motion Analysis (MLVMA at ICCV), 2009. Video clips are compared with a distance function built from patches. The weights of these patches are determined via transfer learning (MLVMA), and used in an efficient action detection framework (ACCV).
William Ma successfully defended his M.Sc. thesis Motion Estimation For Functional Medical Imaging Studies Using A Stereo Video Head Pose Tracking System. Congratulations William!
Yang Wang (PhD) had a paper on human action recognition accepted to IEEE Computer Vision and Pattern Recognition (CVPR), 2009. A hidden conditional random field model is learned using a max-margin criterion.
Mohammad Norouzi (MSc) and Mani Ranjbar (PhD) had a paper on feature learning accepted to IEEE Computer Vision and Pattern Recognition (CVPR), 2009. A hierarchical convolutional variant of the restricted Boltzmann machine model is developed in which parameters are tied to learn filters which are used as features for object detection.
Mark Bayazit (BSc) and Alex Couture-Beil (MSc) had a paper on human gesture recognition accepted to IAPR Conference on Machine Vision Applications (MVA), 2009. An efficient algorithm using the GPU was developed.
Yang Wang (PhD) had a paper on human action recognition accepted in IEEE Transactions on Pattern Analysis and Machine Intelligence (T-PAMI), 2009. A novel bag-of-words sequence model is developed, based on latent Dirichlet allocation (LDA).
Yang Wang (PhD) had a paper on human action recognition accepted to Advances in Neural Information Processing Systems (NIPS), 2008. A hidden conditional random field model incorporating large-scale global features and local patch features is used in this work.
Yang Wang (PhD) had a paper on estimating human pose. Multiple tree-structured models are combined to handle occlusion and avoid "double-counting" of image evidence. This work appeared at the European Conference on Computer Vision (ECCV), 2008.

I was program co-chair for the Fourth Canadian Conference on Computer and Robot Vision (CRV 2007 Montreal).

RESEARCH INTERESTS

My research interests are in computer vision. I research algorithms for automatically interpreting images and videos, particularly those containing people. I am currently working on:
  • human body pose estimation
  • pedestrian detection
  • activity recognition
  • object recognition
  • machine learning
Please see the Vision and Media Lab for a list of research projects, or my list of publications for more details.
