%description
Provides functions for the computation of functional elastic shape means
over sets of open planar curves. The package is particularly suitable for
settings where these curves are only sparsely and irregularly observed. It
uses a novel approach for elastic shape mean estimation, where planar
curves are treated as complex functions and a full Procrustes mean is
estimated from the corresponding smoothed Hermitian covariance surface.
This is combined with the methods for elastic mean estimation proposed in
Steyer, Stöcker, Greven (2022) <doi:10.1111/biom.13706>. See Stöcker et.
al. (2022) <arXiv:2203.10522> for details.
