Research Experience

  • 09/2009 - present:  Computer Vision
    - Supervised by Prof. Antonio Torralba, MIT
    - Scene understanding using a new contextual model.

  • 12/2007 - 09/2009:  Computer Vision
    - Supervised by Prof. Jitendra Malik, University of California - Berkeley
    - Object recognition and detection using various image features. Major works were related to recognitions based on segmentation tree.

  • 08/2006 - 07/2007:  Mobile Sensor Localization
    - Supervised by Prof. Max Welling, University of California - Irvine
    - Proposing a distributive method that estimates sensors' locations and their uncertainties with limited information outside the network (i.e. GPS). This research was about a fully distributed message passing algorithm based on expectation propagation.
