Using Area Voronoi Tessellation to Segment Characters Connected to Graphics
Yalin Wang, Ihsin T. Phillips, Robert M. Haralick · 2001
Little attention has been paid to character connection problems in interpreting the engineering drawings. In this paper, three types of character connection problems are discussed a nd a method using area Voronoi tessellation is proposed to solve problem type II. Using area Voronoi tessellation, we can efficiently determine the contour of the characters and then detect the existence of any characters connected to graphics by hypothes is and validation. Projection analysis is used to segment and validate the characters connected to graphics. The correctness and feasibility of this method is demonstrated.
