Quaternion statistics applied to the classification of motion capture data

作者：

Highlights：

• Quaternion based summary statistics are an efficient tool in motion analysis.

• In most cases, quaternion-based statistics outperform Euler angles ones.

• It is feasible to construct quaternion-based Naïve Bayes classifier.

• Quaternion features preserve strong individual traits.
