The objective of this investigation is to build up a fast orthorectification procedure for high resolution satellite images. The proposed scheme comprises two major components: (1) orbit modeling, and (2) image orthorectification. In the orbit modeling, we provide a collocation procedure to determine the precision orbits. In the image orthorectification, the area of interest is sequentially sub...

Ever increasing advances in the resolution of satellite imagery are matched by commensurate increases in the expectations of the precision of the results emanating from the interpretation of such imagery. This is particularly apparent in the case of urban planning applications of remote sensing techniques to the monitoring of land use changes at a local territorial scale. Clearly it is unreason...

The term “image fusion” covers multiple techniques used to combine the geometric detail of a high-resolution panchromatic image and the color information of a lowresolution multispectral image to produce a final image with the highest possible spatial information content while still preserving good spectral information quality. During the last twenty years, many methods such as Principal Compon...

Pansharpening is a technique that fuses the information of a low resolution multispectral image (MS) and a high resolution panchromatic image (PAN), usually remote sensing images, to provide a high resolution multispectral image. In the literature, this task has been addressed from different points of view being one of the most popular the wavelets based algorithms. Recently, the contourlet tra...

The goal of the Bamiyan project of the Institute of Geodesy and Photogrammetry, ETH Zurich, started in July 2001, is the terrain modeling of the area, the 3D reconstruction of the two lost Buddha statues in Bamiyan as well the actual empty niches and the documentation of the UNESCO cultural heritage site with a topographic and tourist information system. Different types of images, with differen...
