Elliptical

These two functions impliment the system of elliptical Fourier shape descriptors first described by Kuhl and Giardina in "Elliptic Fourier features of a closed contour" Computer Graphics and Image Processing 18:236-258 1982. fEfourier is the forward transform which creates a "shape spectrum" of a...
