Momocs is intended to ease and popularize shape analysis
        of outlines (especially using elliptical Fourier analysis). It
        mostly hinges on the functions developed in Morphometrics with
        R (Claude, 2008). From outline extraction of images and
        elliptical Fourier calculation to multivariate analysis and the
        visualization of transformations within the morphological
        space, Momocs provides a complete and convenient toolkit to
        specialists within every field that are, or may be, interested
        in morphological comparisons of outlines.
