Splits binary object to approximated ellipses using scikit-image

[l.r...@gmx.us]

Hi,

Can scikit-image do ellipse splitting like in an imageJ plugin (http://imagej.net/Ellipse_split) that splits binary object to approximated ellipses?

Thanks,

Lluis

Hi Lluis,

We don't have a built-in function, but it should be relatively easy to build this using:

scipy.ndimage.distance_transform: http://docs.scipy.org/doc/scipy/reference/generated/scipy.ndimage.distance_transform_edt.html#scipy.ndimage.distance_transform_edt

skimage.morphology.watershed: http://scikit-image.org/docs/dev/api/skimage.morphology.html#skimage.morphology.watershed

skimage.transform.hough_circle: http://scikit-image.org/docs/dev/auto_examples/plot_circular_elliptical_hough_transform.html

If you get it working, please post your results back to this list, as they would make a very nice example!

Hope that helps,

Juan.
