Robust Group Synchronization via Quadratic Programming
Yunpeng Shi, Cole Wyeth, Gilad Lerman
We propose a novel quadratic programming formulation for estimating the corruption levels in group synchronization, and use these estimates to solve this problem. Our objective fun…
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…
Ab-initio Contrast Estimation and Denoising of Cryo-EM Images
Yunpeng Shi, Amit Singer
Background and Objective: The contrast of cryo-EM images varies from one to another, primarily due to the uneven thickness of the ice layer. This contrast variation can affect the…
Scalable Cluster-Consistency Statistics for Robust Multi-Object Matching
Yunpeng Shi, Shaohan Li, Tyler Maunu +1
We develop new statistics for robustly filtering corrupted keypoint matches in the structure from motion pipeline. The statistics are based on consistency constraints that arise wi…
