Experience
- Structure From Motion Model of my Car (Development)http://www.leviself.com/viewer/reconstruction.html#file=/subaruall/reconstruction.meshed.json
As part of my many experiments in computer vision, I made this SfM model of my beloved Subaru by taking many snapshots all around. Beware, the link takes a minute to load and you need to zoom out to see what this looks like. I think it's worth it though!
- Silver Medalist @ International Computer Games Olympiad 2009 (Other amazing things)
Long before AlphaGo, I programmed a game engine to play Kriegspiel against other bots at the ICGA. At the time, I was serving as a volunteer in Africa - living in a mud hut without electricity. I won second place and even defeated the institutionally sponsored Beijing Institute of Technology team. I thrive in environments with limited resources and have ample experience punching above my weight!
