How to find the intensity of the given input image

My image is nothing but a road with full of fog. Is there any way to detect the fog alone.

Can you get a good photo of the road without the fog, say from a prior time? Even if it were a different color or intensity you might be able to use that to get rid of it from the foggy image.

Have you looked at any of these articles on fog analysis:
