Witryna17 gru 2014 · 1 Answer. Think of the shape as something you "burn". Thinning is the same as setting all the borders on fire and waiting for a given time. The thinned image is what's left of the image after this time. With the same analogy skeletonizing again sets all the borders on fire but the result are the places where fire fronts meet.
