Research Projects

Personalized television news

Jul. 2012 – Sep. 2013 in DVMM lab, Columbia University

  • Magic Grant Project of the BROWN INSTITUTE FOR MEDIA INNOVATION
  • Bi-coastal research project with students from Stanford and Columbia University
  • In this project, we seek to develop and demonstrate a platform for personalized television news to replace the traditional one-broadcast-fits-all model. We forecast that next-generation video news consumption will be more personalized, device agnostic, and pooled from many different information sources.

Mobile Panorama View from Single Picture

Jul.2010 – Mar.2011 in Microsoft Research Asia

  • Generate panorama view in mobile device by taking one photo.
  • Developed a distributed image retrieval system to get an image collection related with user's input photo. This image collection is used to build panorama view.
  • Parallel computation is used in the cloud to generate panorama view.
  • A predictive cache system is used to speed up panorama viewer in mobile client.

Mobile Experience Sharing through Automatic Multimedia Blogging

Mar.2010 – Jun.2010 in Microsoft Research Asia

  • A "mobile + cloud" system enabling rapid experience sharing through automatic blogging.
  • Based on multi-modal media content analyses and syntheses.
  • A paper and a demo published on ACM MM'10.

Image Based Tree Modeling and Growth Analysis

Jan.2010 – Jun.2010 (Bachelor's Thesis, Zhejiang Univ.)

  • Estimate parameters of tree (i.e. height, diameter, etc.) by building a 3D tree model from video clip.
  • Using the method of 3D object surface reconstruction based on point cloud.
  • Build 3D branch model by manually tracking the key point in video.
  • Excellent Bachelor Thesis Award

Mobile Tour Guide

Jun.2009 – Oct.2009 in Microsoft Research Asia

  • A mobile application which can provide user rich information about the sight he is visiting by taking advantage of a database in the cloud and information from several sensors in mobile phon.
