基于相位编组的道路边缘检测
首发时间:2006-11-27
摘要:遥感影像线状目标的提取在道路识别方面有重要作用。本文针对通常的相位编组研究方法中存在的不足,提出了改进,避免了短直线的产生,另外采用一种稳健的直线拟合方法,得到更为准确的边缘。实验证明,改进后的方法能从影像中更清晰地获得道路边缘。

Abstract:The detecting of remote sensing image plays an important role in roads identification. Aiming at the short comings of the traditional phase-grouping methods, this paper introduces a steady method of Line fitting and more precise edge can be obtained. This method can avoid the production of short line. Experiments prove that the improved methods can better detect the roads edge in the image.
Keywords: remote sensing image feature extraction phase-grouping edge detection
