Topographic correction using brightness normalization approach from hyperspectral remote sensing images

In this paper, we have developed a radiometric brightness normalization based approach by using digital elevation data and local statistics for topographic correction from hyperspectral remote sensing images. Previous approaches for calibration and removal of topographic illumination effect from Hyperspectral and other remotely sensed datasets are reviewed and tested along with the proposed algorithm on a Hyperion image of a study area in Western India. The results indicate that the proposed algorithm is effective in topographic correction.
