  • Title: An improved rotation-invariant thinning algorithm.
    Author: Rockett PI.
    Journal: IEEE Trans Pattern Anal Mach Intell; 2005 Oct; 27(10):1671-4. PubMed ID: 16238001.
    Abstract:
    Ahmed and Ward have recently presented an elegant, rule-based rotation-invariant thinning algorithm to produce a single-pixel wide skeleton from a binary image. We show examples where this algorithm fails on two-pixel wide lines and propose a modified method which corrects this shortcoming based on graph connectivity.
