Paper Abstract

The fusion effect on the high-resolution remote sensing image using the traditional fusion technique such as Principal Component Analysis(PCA), is not satisfying. Considering the well-developed technique of Minimum Noise Fraction(MNF) transform and the flexible ability of Wavelet transform, a new fusion method (MNFWT) integrating MNF and Wavelet transform was studied using multi-spectral (MS) IKONOS image at 4-m spatial resolution and panchromatic (PAN) IKONOS image at 1-m resolution. Compared with PCA fusion method, MNFWT approach performs more efficiently both in improving the spatial information and preserving the spectral information.
