The image quality of airborne photographs is influenced by the atmosphere. Several factors affect the atmosphere, such as temperature, pressure. humidity, and wind speed. Furthermore, these atmospheric influences Bre dependent on the flight altitude. The MTF of the atmospheric Influences and Its dependence on the altitude are examined theoretically and experimentally. Several airborne photographs taken at different altitudes have been evaluated with edge gradient analysis as well as with a grating pattern method. Results are shown. discussed, and compared with model calculations.

Evaluation of the Influence of Exposure Index on Image Quality and Radiation Dose
Introduction: The introduction of digital radiography has led to a significant problem in terms of dose creep. To address this problem, manufacturers have established a set of exposure indicators (EI) as a feedback mechanism to safeguard against overexposure. The EI is the measure of incident exposure to the detector that is directly proportional to the signal-to-noise...

متن کاملAtmospheric Visibility Monitoring Using Digital Image Analysis Techniques
Atmospheric visibility is a standard of human visual perception of the environment. It is also directly associated with air quality, polluted species and climate. The influence of urban atmospheric visibility affects not only human health but also traffic safety and human life quality. Visibility is traditionally defined as the maximum distance at which a selected target can be recognized. To r...
