Riduci le forme binarie a scheletri di 1 pixel di larghezza. Utile per l'analisi della forma, il riconoscimento della grafia e l'estrazione della topologia.
Scheletratizza le forme binarie in linee centrali larghe 1 pixel con l'assottigliamento Zhang-Suen o Guo-Hall per l'OCR e l'analisi delle forme.

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.
