I am a software engineer at Google, trying to develop exciting products using 3D computer vision. My research interests are mainly in 3D reconstruction. See "critical configurations for radial distortion self- calibration" for my most recent work. My resume can be found here.

I was previously a PhD student with Marc Pollefeys and Jan-Michael Frahm at UNC Chapel Hill. After graduation, I have worked as a postdoc with Steve Seitz and Brian Curless at University of Washington. 


VisualSFM : A Visual Structure From Motion System


A Visual 3D reconstruction system that integrates SiftGPU and Multicore Bundle Adjustment. It is easy to use with a feature-packed GUI. Check out my 3DV2013 paper for more algorithmic details:
"Towards Linear-time Incremental Structure from Motion", (webpage, supplemental, video)

 

Open-source Softwares for SfM


Multicore Bundle Adjustment, optimized for both GPU and CPU.

SIFT on GPU (SiftGPU), works for nVidia, ATI and Intel cards.
