Using the difference of the visible light and near infrared band reflectance,the water bodies can be extracted from remote sensing data. 利用可見光和近紅外波段的地物光譜反射率差異可以從遙感數據中提取水體。
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. 老鼠背部皮片舉起前和舉起后的可見光至近紅外線下的多光譜反射率影像被取得。
