Quaternion Information Filters With Inaccurate Measurement Noise Covariance: A Variational Bayesian Method

Abstract: Quaternion Kalman filters (QKFs) are designed for state estimation in three-dimensional (3-D) space. To simplify initialization, this paper focuses on the quaternion information filter (QIF) ...

Minimum Total Quaternion Error Entropy Filtering With Fiducial Points Against Asymmetric Noise

Abstract: Quaternion adaptive filters (QAFs) are extensively used in processing three- or four-dimensional signals effectively. However, their performance can significantly deteriorate or even diverge ...
