Zhu Jianxin Huazhong University of Science and Technology  
The contour vector extraction of scanned engineering drawings is introduced. Moreover, proposed are a fast algorithm of edge-pixel extraction, a method of edge tracing using edge location point for keeping original line′s width, and a contour vector filter against noise. The combination of those approaches make the contour vector of scanned drawings satisfactory.
