Using the difference of the visible light and near infrared band reflectance,the water bodies can be extracted from remote sensing data. 利用可见光和近红外波段的地物光谱反射率差异可以从遥感数据中提取水体。
Visible-near infrared multispectral reflectance image sets were acquired from the dorsal surface of rats both before and after elevation of reversed McFarlane skin flaps. 老鼠背部皮片举起前和举起后的可见光至近红外线下的多光谱反射率影像被取得。
