Abstract :
Our investigation is aimed at analyzing and restoring images of desert and urban scenes that are degraded by the atmosphere. The modulation transfer function (MTF) is used to capture the atmospheric distortion and to remove it. The MTF is estimated from the scene itself from a large discontinuity. The results are presented for various images of the same scene taken under various atmospheric conditions. The restoration is done using the Lucy-Richardson iterative algorithm.
