An automatic algorithm for relative radiometric normalization is presented. It directly normalizes the digital numbers (DN) of images band-by-band to surface reflectance. A united linear relationship from DN of target images to surface reflectance of reference images is derived and the applicable conditions are given. The iteratively re-weighted multivariate alteration detection (IR-MAD) transformation is used to select pseudo-invariant features (PIFs) automatically. The procedure is simple… CONTINUE READING
