| Abstract | ||
| In this paper the TV-satellite images have been analyzed to estimate their quality by usingcontrast of image edges method. The edges of the image have the most important image informationand details that describe its contents. The contrast of edges has been determined using Michelsonformula after modifying it into two different equations based on the mentioned formula. Thismethod has been applied to the TV-Satellite images (same image) from the same channel (AbuDhabi) of different satellites which are Arabsat, Hotbird, and Nilesat. The results show that theimage on Nilesat has the best contrast of edges in the two ways than the images on Arabsat andHotbird. | ||
