摘要
针对二维灰度图象给出了一种获取道路区域的方法。首先基于边缘特性利用灰度直方图把初始生长点限定在道路区以内,然后确定区域生长阈值,以待生长点与已生长邻点的灰度接近性和已生成区域的均值接近性作为生长准则,形成准确的道路区域。
A method of getting road area from2D gray image is presented.Confine the original growing point inside the road area by using gray-level histogram based on edge characteristics.Select thresholds for region growing and form the accurate road area according to the gray-level closeness of the growing point with the grown adjacent point and that of the growing point with the gray average of the grown area.
