NEWS: Area Chair for the Conference on Computer Vision and Pattern Recognition, Nashville, Tennessee, June 2021.

NEWS: Our joint efforts to create large-scale visual localization benchmarks have resulted in a new article, Long-Term Visual Localization Revisited, Toft et al, to appear in PAMI 2021.

NEWS: My PhD student Carl Toft will defend his PhD thesis on January 22, 2021 at 3.00 pm. It will be online, so it is easy to join. Faculty opponent will be Dr. Vladlen Koltun, Intel. Stay tuned.

Interested in the visual localization problem? We have launched a new benchmark site: Visual Localization.
