Rotation Averaging in a Split Second: A Primal-Dual Method and a Closed-Form for Cycle Graphs

ICCV 2021poster

A cornerstone of geometric reconstruction, rotation averaging seeks the set of absolute rotations that optimally explains a set of measured relative orientations between them. In spite of being an integral part of bundle adjustment and structure-from-motion, averaging rotations is both a nonconvex a…

A unified approach for hybrid source localization based on ranges and video

ICASSP 2015accepted

This paper presents a hybrid method for single-source localization in wireless sensor networks, fusing noisy range measurements with angular information extracted from video. Although recent works found in the literature explore hybrid schemes, these include several cumbersome assumptions. We develo…
