The development of Geographical Information Systems applications involving fusion of data from different space-borne imaging sensors inevitably requires a preliminary registration of the images. In case of Synthetic Aperture Radar (SAR) and optical sensors, the registration is particularly challenging due to the vast radiometric differences in the data. In this paper, we present a novel method to register SAR and optical images automatically. It provides an accurate registration despite the radiometric differences in the images. Moreover, this paper introduces a Monte Carlo formulation of the image registration problem.
