Function efd::efd_fitting

pub fn efd_fitting<'a, A>(
    contour: A, 
    n: usize, 
    harmonic: Option<usize>
) -> Array2<f64> where
    A: AsArray<'a, f64, Ix2>, 

Curve fitting using Elliptical Fourier Descriptor.

Giving the contour and the number of output path (n), and the harmonic is the number of harmonic terms, defaults to the Nyquist Frequency of contour.
