Unofficial Home Page for Kelvin Chung

My name is Kelvin Chung. I'm currently working at USC Integrated Media System Center as Research Associate for Prof. Ulrich Neumann and Suya You. I graduated December, 2004 as MS in Integrated Media System with GPA 3.95. Currently I'm working on video surveillance research - Augmented Virtual Environments (AVE System) project. This technology is now commercialized to become Augmented Virtual Earth. Here is the feedback about this technology after LA Tech Week 2007 at USC.

Besides work, I am a member of Chinese Bible Missions Church in Los Angeles and attending Ampelos fellowship. My old web page is still available here.
