The fusion of multispectral images with high spectral and low spatial resolution and panchromatic image with low spectral and high spatial resolution is a very useful technique in various applications of remote sensing. Recently, some studies showed that a wavelet-based image fusion method provides high quality spectral content in fused images. However, most wavelet-based methods yield fused results with spatial resolution that is less than that obtained via the Brovey, IHS, and PCA fusion methods. In this paper, we introduce a novel method of the multiresoution analysis-based image fusion to increase the spatial resolution of fused result. The proposed method simultaneously provides richer information in the spatial and spectral domains. We have been used to merge IKONOS panchromatic and multispectral images.
