Two steps will be successively applied … WebThe Zhang-Suen Thinning algorithm [17], proposed in 1984, is the most widely used and well-proved thin-ning algorithm, because of its robustness. A number of variants of the Zhang-Suen algorithm have also been proposed, e.g. [12, 3, 2]. Zhang-Suen and its follow-ing algorithms are raster-based, making it very compu-tationally expensive. long strich
