Abstract
An improved Pan-sharpening algorithm appropriate to vegetation applications is proposed to fusea set of IKONOS panchromatic (PAN) and multispectral image (MSI) data. The normalized difference vegetation index (NDVI) is introduced to evaluate the quality of fusion products. Compared with other methods such as principal component analysis (PCA), wavelet transform (WT), and curvelet transform (CT), this algorithm has a better trade-off between keeping the spatial and spectral information. The NDVI performances indicate that the fusion product of this method is more suitable for vegetation applications than the other methods.
