| 摘 要： | 针对该类图像,以垂直线段为例,提出一种利用HOUGH变换提取线段的方法。介绍了应用HOUGH变换的基本原理,定义了"基本线"和"附加线"的概念,提出把"附加线"从参数空间剔除的"交点准则",补充了应用过程中对"斜线竞争优势"的消除方法。通过对例图的处理,取得很好的结果。

| Abstract: | In this paper,author provide a new way to extract lines(vertical lines as example) from images based on HOUGH transform..author introduces the basic theory of HOUGH transform firstly,and then defines "prime line" and "additional line",offers the "intersection principle" to eliminate "additional line" out of parameter space,at last explains how to avoid "competition predominance of declining line" in applications.It is proved feasible by processing the sample image. |
