Abstract

An approach to vectorizing binary image of engineering drawing, specially irregular shape is presented in this paper. The preliminary steps include detection and elimination of noise components and skewness. Lines, circles and arcs are detected using existing Hough, transform and chain method is used for both bounded and unbounded irregular shapes.
