ethod based on probability property model including selecting the next line tracking pixel and the first line mergence procedure. This method can satisfy maximum line extending principle , and can reduce line paper realizes the Vectorization of conic , circle and arc using curve fitting method. This line vectorization method can recognise line width order to improve the effect of image and the exactitude of vectorization, this dissertation supplies raster image edition and vector graphics edition, which can make pixel operation and amend image vectorization results. At the same time it supplies the image transform to the form of CAD and can be edited and modified in the condition of dissertation has just carried on the simple try in the Engineering drawing ectorization respect, too. There are a lot of Zheshuai (Communications Information Engineering amp。 本文在工程圖紙矢量化方面只是進(jìn)行了簡單的嘗試,還存在許多問題,有待于進(jìn)一步完
