基于矢量化的二值工程图符号提取算法
Symbol Extraction Algorithm of Binary Engineering Drawings Based on Vectorization
【摘要】 工程图符号提取是工程图识别的重要步骤 .文中提出一种矢量化算法 ,该算法可以将工程图转换成图的表示法 .在该矢量化算法的基础上 ,又提出一种符号提取算法 ,这种算法可以有效地提取各种孤立和粘连符号
【Abstract】 Extracting symbols is an important step in the engineering drawing recognition. This paper presents a vectorization algorithm, which can transfer engineering drawing to a graph. Based on this vectorization algorithm this paper presents a symbol extraction approach which can extract all kinds of isolated and adhered together symbols effectively.
