This paper presents the results of a study led by the CNES (French Space Agency) to compare several panchromatic/multispectral fusion methods. Five fusion methods have been selected and evaluated quantitatively and qualitatively. The quantitative results are obtained through analysis of variance; while fusion is evaluated qualitatively by visual experts.(More)
— Very high spatial resolution images are now available (about 1m), and processes such as classification or seg-mentation are less efficient on this kind of images. This paper proposes a method for pre-processing images, which smoothes the heterogeneous areas but perserves the borders of main objects. This process is done by 1. a multi-resolution non-linear(More)
L'arrivée des images de télédétection à très haute résolution spatiale impose de reconsidérer les méthodes de description des surfaces représentées dans les images satellites. En effet, la précision de la perception disponible peut désormais permettre, sous réserve de la qualité du support, de discriminer les entités composant un paysage. Dans ce contexte,(More)
