- Aug. 2013: New TR (arXiv) on compact reformulations for many-label problems.
- April 2013: Our TPAMI submission is accepted!
- Feb. 2013: My AISTATS submission and 2 CVPR submissions accepted!
- Aug. 2012: A preprint of my ECCV submission on discrete-continuous MRFs is online.
- July 2012: A web page on the connection between continuously inspired and local polytope relaxations for labeling problems (a.k.a. MRFs) is available
(see also the updated TR).
- Dec. 2011: I am going to join the Machine Learning and Perception group at MSR Cambridge in January 2012.
- Dec. 2011: Updated SfM code to version 1.1. Most relevant changes:
- Added more general non-linear least squares optimizer enabling more general instances of bundle adjustment (see V3D/Math/v3d_nonlinlsq.h).
This one relaxes the assumption of the bipartite structure of unknowns as in standard BA (e.g. cameras and 3D points).
The Levenberg-Marquardt implementation plus the corresponding bundle adjuster is also available as separate zip package
(requiring only SuiteSparse as dependency).
- VLFeat and OpenCV can now be used for SIFT feature extraction (in addition to SiftGPU).
- Changed license to LGPL.
- Oct. 2010: full structure-and-motion code available.
- Since Sep. 2009 I am working in the
Computer Vision and Geometry Group at ETH, Zürich
- GPU-based KLT tracker updated to version 1.2
My main research interests include
- Structure from motion techniques
- Dense 3D model generation from images
- Computer vision methods accelerated by graphics processing units
Fore more detailed information on recent work see my research page
The following open source software packages are available:
- SfM — Structure-and-motion code
- SSBA — Simple Sparse Bundle Adjustment
- GPU-KLT+FLOW — Efficient tracking of features in exposure varying videos using the GPU, dense TV-L1 optical flow.
