Abstract: Abstract A new physically based method to estimate hemispheric-directional reflectance factor (HDRF) from lightweight multispectral cameras that have a downwelling irradiance sensor is presented. It combines radiometry with photogrammetric computer vision to derive geometrically and… read more here.

Abstract: Leaf bidirectional reflectance distribution function (BRDF) is partly controlled by the specular reflection from the leaf surface, which does not convey information about leaf biochemical parameters. Therefore, vegetation remote sensing can benefit from understanding the… read more here.
