Paper Abstract

A new approach for vectorization of line drawings is proposed. In this paper, contour vectorization is first applied to convert the scanned image of drawings from raster form to vector form. After the operation of contour matching, elements of skeletal vector and sub- shape are obtained. On the basis of the two types of elements, a graph G(V,E) is built up to help analyze the forked joint in line drawings, and the method of curve tracing and splitting is also discussed to fulfill the sub-optimal extraction of line and arc segments. In addition, experimental results are given showing better results than that of the traditional thinning approach.
