# Skeletonization¶

The nodelet is used to obtain the single pixel skeleton of either edges, contours or regions. An important use of this nodelet is to fix broken edges on 2D image by first applying Dilation operation to the edges such that the broken edges intersect. By using skeletonization, the dilated image single pixel skeleton structure can be obtained. Note that this is different from erosion, as erosion erodes the edges without preserving the structure.
