Improved Morphological Skeleton Extraction Algorithm
Yang Liu · Jisuanji gongcheng · 2009
On the spur of the limitation that the conventional morphological skeleton extraction algorithms fail in poor connectivity,thickness and complicated structure,an improved morphological skeleton extraction algorithm is proposed.Morphology operation and connectivity-preserving strategy are combined in the novel algorithm during the shrinking process to prevent the extracted skeleton from being broken up.Two post-processing strategies,one-pixel thickness thinning and biased skeleton trimming,are also involved to enhance the performance of this improved method.The new algorithm is thus superior to the conventional one.Simulation tests verify the effectiveness of the algorithm.
