Paper Abstract

Vectorizing the skeleton of a binary digital image is important for recognizing drawings and maps. A new vectorization method, based on the energy minimization principle, is proposed in this paper. The method involves thinning, line segment approximation, and geometric transformation. The skeleton line, obtained after the line segment approximation process, includes shape distortion caused by thinning. In the geometric transformation process, the line segments are shifted for minimizing the value, defined in the neighbor of each corner, junction, and so on, by the smoothness and the difference between line segments and skeleton of an original image. The proposed method has an advantage of reducing the various kinds of distortions, compared with the conventional methods.
