Thinning reduces a binary shape to a 1-pixel-wide representation (skeleton) while preserving the topology and connectivity. It is the morphological equivalent of finding the
Zhang-Suen is the classic iterative algorithm and works well for most shapes. Guo-Hall is a one-pass variant that can produce slightly different skeletons — it is faster but may leave more staircase artifacts.
