Paper Abstract

An adaptive multi-spectral and panchromatic remote sensing images fusion method 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-wavelet transform based fusion method is better than ordinary wavelet transform based fusion method, IHS fusion method and PCA fusion method. Different decomposition levels of multi-wavelet transform may lead to different images fusion performance. An adaptive multi-wavelet transform based fusion scheme is presented in this paper. Experiment results show that the adaptive multi-wavelet transform based fusion method can determine the best multi-wavelet decomposition level and provide the best fusion results.
