Hi,<div><br></div><div>Does anyone know if an algorithm to take an endpoint of a binary line in an image and 'walk' back along the line for N pixels already exists in skimage? (or in any of the related projects). I'm happy to go ahead and implement it, but it seems like the kind of thing that would have already been implemented, even though I can't find it in the documentation.</div><div><br></div><div>Does this already exist?</div><div><br></div><div>Cheers,</div><div><br></div><div>Robin</div>
