For IKONOS imagery, both multi-spectral and panchromatic data are provided with different spatial resolutions. In order to produce multi-spectral images with high spatial resolution, a number of panchromatic sharpening methods have been developed. However, the classical methods such as IHS, PCA and Brovey transform often introduce severe color distortion due to injecting undesired low-pass component of panchromatic observation into the fused multi-spectral images. Recent methods employing the… CONTINUE READING
