Orientation Estimation of Cryo-EM Images for Molecules with Arbitrary Symmetry by Semidefinite Programming
Yunpeng Shi, Amit Singer, Jinxin Wang +1
This paper extends the non-unique games framework introduced in Bandeira et al. (2020) to address symmetric structures. Precisely, we consider the problem \[ \begin{aligned} \under…

TriDE: Triangle-Consistent Translation Directions for Global Camera Pose Estimation
Francisco Chen, Yiran Wang, Yunpeng Shi
Pairwise translation directions are a key input to camera location estimation in global structure-from-motion. Existing estimators usually process each image pair independently, pr…

TriP: A Triangle Puzzle Approach to Robust Translation Averaging
Zhekai Fan, Wanze Li, Jinxin Wang +1
Translation averaging aims to recover camera locations from pairwise relative translation directions and is a fundamental component of global Structure-from-Motion pipelines. The p…
