geeSharp.js:一个库，用于在Google Earth Engine中泛锐化多光谱图像并评估图像质量

geeSharp GEE中的Pan-harpen多光谱图像，只需一行代码： var panSharpened = sharpening . PCA . sharpen ( img . select ( [ "B4" , "B3" , "B2" , ] ) , img . select ( [ "B8" ] ) ; 生成图像质量指标以验证锐化结果： var imgQ = quality . Q . calculate ( originalImage , panSharpened ) ; 安装 通过包括var sharpening = require("users/aazuspan/geeSharp:sharpening.js");导入锐化函数var sharpening = require("users/aazuspan/geeSharp:sharpening.js"); 在您的脚本
