Abstract
Methods and systems in accordance with the present invention provide a continuum measure of visibility from a single image without prior knowledge of the camera system or the cameras in the system. This may be, for example, a score on the weather visibility quality of the image, ranging from good to poor, or a numeric score representing the weather visibility quality of the terrain in the image. This may be done without prior knowledge of the camera system, the camera that took the image, or the environment. It is also done with the single image without using multiple images, or reference images. The system derives a real-time continuum measure of visibility from a single daytime image, with unknown camera quality, system configuration, and environmental conditions.
