摘要
遥感影像上线状地物的提取是影像处理的主要研究内容之一。通过对线状地物形状特征的分析,将其抽象为长矩形,设定长宽比阈值,进行线状地物提取,取得不错实验结果。
Linear Feature Extraction of remote sensing images is the main research content of remote sensing data processing. Analyzed the shape feature of linear feature, abstracted it as long rectangular, set the threshold of length -width ratio, extracted the linear feature, and got good experimental results,
