The quaternion cubature Kalman filter (QCKF) algorithm has emerged as a prominent nonlinear filter algorithm and has found extensive applications in the field of GNSS/SINS integrated attitude ...

If you have data gathered in one coordinate system and want to express them in terms of a different coordinate system, you probably would use a translation vector and a rotation matrix. You can, ...

I'm interested in using a pow/exponent function on the Quaternion type to concisely represent repeated rotations. For quaternions specifically, I found an algorithm for this on the Mathematics ...

Electroencephalography (EEG)-based emotion recognition holds significant potential in affective brain–computer interfaces. However, substantial inter-subject variability—due to differences in skull ...

Abstract: In this paper, a novel quaternion adaptive filtering algorithm is proposed for a unified processing of 3D and 4D data, called quaternion least mean kurtosis (QLMK) algorithm.

ABSTRACT: This paper aims to present, in a unified manner, the algebraic techniques of eigen-problem which are valid on both the quaternions and split quaternions. This paper studies eigenvalues and ...
