This article presents the assessment of the fusion of Ikonos satellite images using two methods, the first corresponds to the Brovey Transform and the second Multiplication method implemented in the Matlab Software, with the objective of identifying which of the two methods improves the special resolution without significant loss of spectral richness. Assessment of two implemented methods were performed using the following indices: ERGAS (spectral and spatial), RASE, Universal QualityIndex Qu, and Correlation Index, where the best results on spatially and spectrally richness were obtained with first method called transform Brovey.
