Paper Abstract

We show that global and local characteristic features of thermal images undergo considerable diurnal changes. In particular, the standard deviation of the gray-level distribution of thermal images increases with the intensity of the solar flux and the diversity of the microtopography, while the spatial correlation length decreases under the same conditions.
