QuadSync: Quadrifocal Tensor Synchronization via Tucker Decomposition
Daniel Miao, Gilad Lerman, Joe Kileel
In structure from motion, quadrifocal tensors capture more information than their pairwise counterparts (essential matrices), yet they have often been thought of as impractical and…
Cycle-Sync: Robust Global Camera Pose Estimation through Enhanced Cycle-Consistent Synchronization
Shaohan Li, Yunpeng Shi, Gilad Lerman
We introduce Cycle-Sync, a robust and global framework for estimating camera poses (both rotations and locations). Our core innovation is a location solver that adapts message-pass…
Tensor-Based Synchronization and the Low-Rankness of the Block Trifocal Tensor
Daniel Miao, Gilad Lerman, Joe Kileel
The block tensor of trifocal tensors provides crucial geometric information on the three-view geometry of a scene. The underlying synchronization problem seeks to recover camera po…
Efficient Detection of Long Consistent Cycles and its Application to Distributed Synchronization
Shaohan Li, Yunpeng Shi, Gilad Lerman
Group synchronization plays a crucial role in global pipelines for Structure from Motion (SfM). Its formulation is nonconvex and it is faced with highly corrupted measurements. Cyc…
A Subspace-Constrained Tyler's Estimator and its Applications to Structure from Motion
Feng Yu, Teng Zhang, Gilad Lerman
We present the subspace-constrained Tyler's estimator (STE) designed for recovering a low-dimensional subspace within a dataset that may be highly corrupted with outliers. STE is a…
Fast, Accurate and Memory-Efficient Partial Permutation Synchronization
Shaohan Li, Yunpeng Shi, Gilad Lerman
Previous partial permutation synchronization (PPS) algorithms, which are commonly used for multi-object matching, often involve computation-intensive and memory-demanding matrix op…
