Fusion process: merge images through Dual Tree Complex Wavelet transform (DT-CWT). MS bands were merged with the panchromatic band, getting new bands with a resolution of 15 meters (m). The fusion process applied are summarized in [13]:. (a) Radiometric correction and resample the MS image so that their bands have the same pixel size as the PAN image. (b) These bands, along with the PAN are decomposed by means of DT-CWT. (c) Preserve MS Approximation. (d) The PAN detail coefficients are compared with the respective MS coefficients and the highest are used as they describe the high frequency component
