Paper Abstract

This paper examines the shadow extraction problem associated with satellite images; namely the shadow component of the images. The present research extends our previous work on shadow extraction in simple scenes. Extraction of multivariable shadows caused by earth's rotation and satellite viewing angle is examined. Attempt is made to define the variables of such shadow component in a controlled lab environment in terms of the phase of the Fourier spectrum of the image, device a novel method for extracting complex shadow components from the image, and to create a meta-image suitable for change detection post processing.
