一种智能化SAR图像道路检测方法
n New Intelligent Method of Road Extraction in SAR Images
本文提出了一种新的星载合成孔径雷达（SAR）图像中道路网的三步提取算法，即道路中心线检测、道路片段提取与道路片段连接。首先对含有斑点噪声的SAR图像进行两次滤波获得较细的道路中心线，然后对该二值图像进行Hough变换以获得道路片段，道路片断经过简单的初步连接后，再次运用遗传算法进一步连接。
his paper presents a new three-step algorithm for road network detection in a spaceborne synthetic aperture radar (SAR) image, that is, detection of road central line, extraction of road segments and grouping of road segments. First we acquired thin road central lines after two times of filtering of the SAR image which has many speckles. Then we used Hough transformation to the bi-valued SAR image and acquired road segments. After simply initial grouping, the road segments were farther grouped using genetic algorithm
