The objective of skeletonization is to represent a binary image with a minimum set of pixels. The skeleton must account for geometrical properties of the form and retain associative relationships.

My question here is how can I get a skeleton from binary image?

%# assume your binary image is called binImg
skeleton = bwmorph(binImg,'skel',inf);
