Abstract :
Theoretical work has shown that meteorological range, a standard measure of visibility, can be related to changes in contrast in the spatial domain of a scene, and changes in the non-zero frequencies of its frequency response. The present work employs aircraft images of mountain scenes to show that changes in the energy of non-zero frequencies trace a decaying exponential curve whose logarithmic slope describes the meteorological range for that particular scene
