Vectorization Technique Based On Object-Oriented Knowledge

Computer image processing is an important branch not only in Computer graphics but also in computer technology. In terms of mechanical engineering drawings or technological drawings, it deals with a series of digital figures in the process of conversion from storage with paper to computer.Concentrating on the technology of raster to vector conversion, the paper begins with an analysis of the process of raster to vector conversion, followed by the analysis, comparison, and realization of the algorithms in all stages of raster to vector conversion, including scanning, image binarizing, noise-reducing, separation of text from graphics, line vectoring, arc vectoring, as well as an improvement of several algorithms. In the end, the file format of drawing exchange file (DXF) of AutoCAD is analyzed and the vector results are input and then transferring them into the vector files which can be used by CAD software.
