Abstract

Background images of a typical Mediterranean landscape were measured for 24 hours and their properties were analyzed. The locations were chosen to represent an area with various amount of vegetation. The thermal mean and variance changes around the clock were extracted from these background images and a typical pattern for the variance behavior was identified. A simple model is suggested for describing this behavior. The knowledge of variance dependence on the scene and measurement system parameters could be further used for simulation of IR images or for detection probability estimation.
