Abstract :
In remote sensing applications there is a need of an image with high spatial resolution and high spectral resolution. To obtain this kind of image the panchromatic image is fused with the multispectral image using hybrid transform. The basic ideas behind this method is that the extraction of the spectral information from the multispectral image and fuse this information with the new intensity component obtained from the radon transform of panchromatic and multispectral image. The fusion used in this method is maximum coefficient scheme, which takes the largest magnitude while comparing. In this fusion method, higher value Radon transformed coefficients of intensity component are injected. To this, hue and saturation components are added. So High Resolution Multispectral Image (HRMI) is obtained with high spectral and spatial quality which is better than the image obtained from IHS method.
