EXTRACTION OF LINE-ELEMENT BASED ON SEGMENT CONNECTIVITY
Huarong Li · Cehui dili xinxi · 2010
A non-precise reasoning method used of differences in the characteristics of segment connectivity is put forward for separating line symbols from other symbols.Using line adjacency relations,seven kinds of easy-to-expression characteristic parameters are presented according to the differences in geometrical features,shape features and topologic relationship.The parameters are estimated step by step and line-elements are automatically extracted.
