coo_oscillo

Shape analysis deals with curve fitting, whether \(x(t)\) and \(y(t)\)
positions along the curvilinear abscissa and/or radius/tangent angle variation.
These functions are mainly intended for (self-)teaching of Fourier-based methods.

The goal of 'Momocs' is to provide a complete, convenient,
reproducible and open-source toolkit for 2D morphometrics.
It includes most common 2D morphometrics approaches on outlines, open outlines,
configurations of landmarks, traditional morphometrics, and facilities for data preparation,
manipulation and visualization with a consistent grammar throughout.
It allows reproducible, complex morphometrics analyses and other morphometrics approaches
should be easy to plug in, or develop from, on top of this canvas.
