| 摘 要： | TM数据经典水体提取方法存在对细小水体的漏判和对山体阴影的误判两方面缺陷。本文基于LBV变换提出了B分量阈值法和LBV关系法两种新的水体提取方法。实验结果表明:两种新方法的漏分精度分别为2.54%、2.73%,误分精度分别为15.71%、13.39%,整体提取效果优于经典方法。

| Abstract: | The classical methods for water body extraction from TM data have two shortcomings including omission of small water and misidentification of mountain shadows. In this paper, two new methods based on LBV transformation: threshold of B component and relations among L, B and V components were proposed. The experiment result showed that the proposed methods provided feasible and effective ways for water body extraction. |
