Uncertainty characterization of the orthogonal Procrustes problem with arbitrary covariance matrices

作者:

Highlights:

• The uncertainty present in the n-dimensional Procrustes problem is characterized.

• Perturbation theory allows the determination of the covariance of the solution.

• The method is demonstrated for several dimensionalities on synthetic data.

• The effects of the number of points, baseline, and covariance shapes are detailed.
