Abstract:
A new fusion methodology for Multiespectral and Pancromatic images, has been proposed. This methodology is based on a joint multiresolution-multidirectional representation of the source images. For that an unique directional filters bank of low computacional complexity has been used.This kind of image representation allows an appropriated selection of the information extracted from the source images, avoiding some of the limitations inherent to other multiresolution fusión methods. The final aim is to obtain fused images with a high spectral and spatial quality simultaneously. The source images corresponds to the captured by Quickbird satellite (panchromatic and multispectral). The high quality of the obtained results shows the potential of the joint multiresolution-multidirectional representation for images fusion.
