Fusion of High Spatial and Spectral Resolution Images Based on Spatial Domain and Multiresolution Analysis
Image fusion is one of the important techniques to enhance image information of remote sensing. In order to adequately make use of all kinds of remote sensing images information such as Panchromatic and three-band multi-spectral images, a novel remote sensing image fusion scheme based on wavelet transform is proposed. The fusion of Multi-Spectral (MS) and PANchromatic (PAN) images, with complementary spectral and spatial characteristics, is becoming a promising technique to obtain images with high spatial and spectral resolution simultaneously. Several commercial earth observation satellites carry dual-resolution sensors, which provide high spatial resolution panchromatic image and low spatial resolution multispectral image.
