Reflectance function
WebSpectral reflectance is generally retrieved considering the observed target as a Lambertian and homogeneous diffuser for which the upward radiance can explicitly be expressed as a function of surface reflectance (Barducci and Pippi, 1994; Qiu, 2001). Although many surfaces behave similarity to an ideal diffuser, WebDescription example newhcube = radiance2Reflectance (hcube) converts the pixel values of the hyperspectral data cube from radiance to reflectance values. The function returns a new hypercube object and the pixel values of the data cube represent the top of atmosphere (TOA) reflectance. For more information, see TOA Reflectance.
