Tools for working with ellipses in Python.
Should be an easy pip install:
pip install ellipsinatorTo fit an ellipse:
from ellipsinator import fit_ellipse_halir
c = fit_ellipse_halir(x, y)
from ellipsinator import fit_ellipse_fitzgibon
c = fit_ellipse_fitzgibon(x, y)
from ellipsinator import fast_guaranteed_ellipse_estimate
c = fast_guaranteed_ellipse_estimate(x, y)You can also pass in the measured points as a complex number, `x + 1j*y`:
from ellipsinator import fit_ellipse_halir
c = fit_ellipse_halir(x)Fitting multiple ellipses simultaneously is also possible with fit_ellipse_halir and `fast_guaranteed_ellipse_estimate`:
assert x.shape == (num_ellipses, num_pts)
assert y.shape == (num_ellipses, num_pts)
c1 = fit_ellipse_halir(x, y)
c2 = fast_guaranteed_ellipse_estimate(x, y)
assert c1.shape == (num_ellipses, 6)
assert c2.shape == (num_ellipses, 6)
