Abstract
Multi-spectral and panchromatic remote sensing images fusion is discussed. High spatial resolution panchromatic image can provide detail geometric features ,while multi-spectral image can provide very good spectral information. A high spatial resolution multi-spectral image can be obtained by combining these two images. Multi-wavelets can be simultaneously orthogonal, symmetric, short supported and of high vanishing moments, all these properties can be used to maintain spatial information of panchromatic images and spectral information of multi-spectral images. A multi-wavelet transform based fusion scheme is presented in this paper. Experiment results show that the multi-wavelet transform based fusion method is better than the ordinary wavelet transform based fusion method and is superior to IHS fusion method and PCA fusion method. The fused image can provides more spatial information.
