Implementing Robust M-Estimators with Certifiable Factor Graph Optimization
Zhexin Xu, Hanna Jiamei Zhang, Helena Calatrava +2
Parameter estimation in robotics and computer vision faces formidable challenges from both outlier contamination and nonconvex optimization landscapes. While M-estimation addresses…
Label Hijacking in Track Consensus-Based Distributed Multi-Target Tracking
Helena Calatrava, Shuo Tang, Pau Closas
Distributed multi-target tracking (DMTT) in limited field-of-view (FoV) sensor networks commonly suffers from label inconsistency, whereby different nodes disagree on the identity…
Cooperative Differential GNSS Positioning: Estimators and Bounds
Helena Calatrava, Daniel Medina, Pau Closas
In Differential GNSS (DGNSS) positioning, differencing measurements between a user and a reference station suppresses common-mode errors but also introduces reference-station noise…
