摘要
矢量编码在工程图自动读入系统中占有很重要的地位，本文提出了一种新的矢量编码方法，这种基于两正交向行邻图（ＬＡＧ）进行边缘检测的矢量编码方法，它可以克服单一方向边缘检测的缺点，较好地保留了线段的边缘信息，并具有效高的数据压缩率。文章将论述这一方法的形成、特点及算法，最后给出经矢量编码、模式织别后输出的原图。
Vector encoding plays an important role in the Automatical read-in systems of engineering drawings.In this paper,we present a new method of vector encoding. It is based on the edge detection along the two-orthogonal LAG. The method has the advantages of high data compress and good edge effect, which can overcome the deffect of one direction LAG. We'll explain its form,feature and its algorithm in the paper. Finally,a graphy by means of RTV and recognition is given.
