Robust Single Rotation Averaging

open access: yes, 2020
We propose a novel method for single rotation averaging using the Weiszfeld algorithm. Our contribution is threefold: First, we propose a robust initialization based on the elementwise median of the input rotation matrices. Our initial solution is more accurate and robust than the commonly used chordal $L_2$-mean.

A Robust Incremental-Quaternion-Based Angle and Axis Estimation Algorithm of a Single-Axis Rotation Using MARG Sensors

open access: yesIEEE Access, 2018
A robust incremental-quaternion-based algorithm is proposed in this paper to estimate the angle and the axis of a single-axis rotation whose rotation axis is invisible or inaccessible.

Rapid Rotation in the Kepler Field: Not a Single Star Phenomenon [PDF]

open access: yesAstrophysical Journal, 2018
Tens of thousands of rotation periods have been measured in the Kepler fields, including a substantial fraction of rapid rotators. We use Gaia parallaxes to distinguish photometric binaries (PBs; from single stars on the unevolved lower main sequence ...
