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(jiàn)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(jiàn)光至近紅外線(xiàn)下的多光譜反射率影像被取得。
