Honey, I Shrunk the Arc de Triomphe!
Yuanbo Xiangli, Hanyu Chen, Xueqing Tsang +1
Metric scale monocular geometry estimation has seen significant progress through large-scale data aggregation, yet current foundation models suffer from a persistent ''scale-collap…
ArchSym: Detecting 3D-Grounded Architectural Symmetries in the Wild
Hanyu Chen, Ruojin Cai, Steve Marschner +1
Symmetry detection is a fundamental problem in computer vision, and symmetries serve as powerful priors for downstream tasks. However, existing learning-based methods for detecting…
Doppelgangers++: Improved Visual Disambiguation with Geometric 3D Features
Yuanbo Xiangli, Ruojin Cai, Hanyu Chen +2
Accurate 3D reconstruction is frequently hindered by visual aliasing, where visually similar but distinct surfaces (aka, doppelgangers), are incorrectly matched. These spurious mat…
3D Reconstruction with Fast Dipole Sums
Hanyu Chen, Bailey Miller, Ioannis Gkioulekas
We introduce a method for high-quality 3D reconstruction from multi-view images. Our method uses a new point-based representation, the regularized dipole sum, which generalizes the…
Objects as volumes: A stochastic geometry view of opaque solids
Bailey Miller, Hanyu Chen, Alice Lai +1
We develop a theory for the representation of opaque solids as volumes. Starting from a stochastic representation of opaque solids as random indicator functions, we prove the condi…
