A fast technique for vectorization of engineering drawings using morphology and digital straightness

摘要: A novel technique for vectorization of engineering drawings is presented. The novelty the algorithm lies in exploiting certain digital-geometric properties straightness to vectorize inclined line segments and curve after vectorizing horizontal vertical pieces using conventional morphological opening. primitives, hence vectorized, are classified into (i) horizontal, (ii) vertical, (iii) segments, (iv) curved segments. Such a classification expedites reconstruction an drawing from vector format. Experimental results on several benchmark datasets have been given demonstrate its efficiency elegance.
