本文对从landsat影像中提取细小水体的方法作了研究,基于ERDAS软件用新的识别方法提取较小水体。利用谱间模型提取TM影像中较大水体,再将TM影像中某3个波段组成的假彩色合成图转换到IHS彩色空间,构建模型提取细小水体,并与前者识别结果进行叠加,获得较好效果,证明在实际中可用。
本文對從landsat影像中提取細小水體的方法作瞭研究,基于ERDAS軟件用新的識彆方法提取較小水體。利用譜間模型提取TM影像中較大水體,再將TM影像中某3箇波段組成的假綵色閤成圖轉換到IHS綵色空間,構建模型提取細小水體,併與前者識彆結果進行疊加,穫得較好效果,證明在實際中可用。

The method of small water extraction is discussed in this paper,using a new method based on ERDAS to extract small water.We extract main water-body by spectrum model,and take the false synthetic figure which consist of three bands of color in the HIS color space,then construct the model of small water extraction,united results which extracted from those models.Results from empirical studies,applying this method is useful.
