Abstract

This paper examines the shadow extraction problem associated with satellite images; namely the fact that images taken at a different time include different shadow components. In the present research we attempt to define the shadow component of an image in a controlled lab environment in terms of the phase of the Fourier spectrum of the image, devise a novel method for extracting the simple shadow component from the image, and to create a meta-image suitable for change detection post processing.
