In this paper we describe an application of the extended radiosity method to compute atmospheric scattering effects over heterogeneous surfaces and to perform the inverse operation: to correct for such atmospheric effects. The radiosity method is used to compute point-spread-functions. (PSF's) which determine how much light is scattered from an adjacent surface into the field-of-view (FOV) of a sensor above the atmosphere. We show that the PSF's are in general asymmetric for pointable airborne or satellite sensors. A Fourier transform based method can be used to correct adjacency-effect-blurred images for these atmospheric distortions.
