Pixel based image fusion entails combining geometric details of a high-resolution Panchromatic (PAN) image and spectral information of a low-resolution Multispectral (MS) image to produce images with highest spatial content while preserving the spectral information. This work reviews and implements six fusion techniques – À Trous algorithm based wavelet transform (ATW), Mulitresolution Analysis...

Method for 3D map creation based on knowledgebase system for texture mapping together with height estimation using objects’ shadows with high spatial resolution of remote sensing satellite imagery data is proposed. Through the experiments with IKONOS imagery data, the proposed method is validated. Keywords—texture mapping; remote sensing satellite; 3D map; object height estimation;

Due to the increasing demand and use of digital spatial information, the interest is being drawn to the generation of digital orthophotos, which is the most accurate and reliable source of spatial information. The subject of this project is the generation of orthoimages as well as the further processing of these orthoimages for the full exploitation of their spectral and spatial information. Th...

Now to ensure the quality of automatic extraction of buildings from aerial and space imagery is not comprehensively understood. Dedicated efforts are needed in examining both the theoretical and practical aspects of the problem. This paper first presents a review of building extraction research activities, with the focus on quality-related issues. Also addressed is recent progress in the use of...

We attempted a method of fusing a coarse resolution hyperspectral image and a high spatial resolution image with a few spectral bands to produce a high resolution hyperspectral image, and to extract the spectra of the end-members. The method is based on the linear spectral mixing model and an iterative maximum-likelihood algorithm is used to invert the mixing equation. The effects of noise and ...

In monitoring vegetation change and urban planning, the measure and the mapping of the green vegetation over the Earth play an important role. The normalized difference vegetation index (NDVI) is the most popular approach to generate vegetation maps for remote sensing imagery. Unfortunately, the NDVI generates low-resolution vegetation maps. Highresolution imagery, such as IKONOS imagery, can b...
