ellipsinator 0.1.0

Ellipse tools for Python

Ellipsinator

Tools for working with ellipses in Python.

Installation

Should be an easy pip install:

pip install ellipsinator

Usage

To 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)

The only function that supports fitting multiple ellipses simultaneously is fit_ellipse_halir:

assert x.shape == (num_ellipses, num_pts)
assert y.shape == (num_ellipses, num_pts)
c = fit_ellipse_halir(x, y)
