Article. WebI would propose using a distance transform. So once you've got your labeled image you do: dt = ndimage.distance_transform_edt (blobs) slices = ndimage.find_objects (input=labels) radii = [np.amax (dt [s]) for s in slices] This gives the largest inscribed circle (or sphere in 3D). The find_objects function is quite handy.
