If that's the case, maybe this paper is of some help: https://www.researchgate.net/publication/276433770_Multiple_ellipse_fitting_by_center-based_clustering/fulltext/56293cc208aef25a243d5d3a/Multiple-ellipse-fitting-by-center-based-clustering.pdf I imagine you'd need to program this yourself. -- Chris Hermansen · clhermansen "at" gmail "dot" com C'est ma façon de parler.
