摘要
图像的边缘在局部是具有一定方向的,如何根据图像边缘方向的不同计算相应的边缘检测模板,来抑制其他方向的干扰,取得感兴趣的方向边缘,从而为以后的行二值化、线条细化、删除短线、矢量跟踪、直线提取等图像处理打下基础,是本文要解决的问题。并且通过其在道路半自动提取中的应用来验证方向模板的使用效果。
The edge of the image has quite certain directions. This paper is to solve the problem, how to calculatc the corresponding edge detection templates based on the different direction of the image edges, meanwhile inhibit other direction interfcrence and obtain the fringes of interest direction, and lay down the groundwork for the future image processing, such as： thc binary of the fringes, the line refinement, deleting the short lines, the vector tracking, and extracting the straight lincs ctc. , which are the main problems to be solved in this paper. At the same time, through semi-automatic extraction of road direction to test the effectiveness of use of templates.
