Abstract:

The purpose of the Satellite Image Quality Simulation was to develop a quantitative model for the relationship between the subjective quality of images of satellites obtained through a turbulent atmosphere from large ground based telescopes, and quantitative measures of the optical transfer function and noise characteristics of the image formation process. To determine this relationship, a series of images of satellites was generated in the study, in which the effects of various OTF and noise degradations were simulated. The images were viewed by a group of human observers, who were asked to estimate the subjective quality of the images, relative to a set of reference images of the same satellite having known resolution characteristics. The results of these viewing and interpretation experiments were then compared to the predictions of several image quality models one model was found to produce a very good fit to the observed data.
