Hi, I assume you are trying to find fog density, prior to defogging the foggy image.
A function named imreducehaze() comes inbuilt starting from MATLAB 2017b. This function returns fog density at each pixel of an image. The following code might help.
A = imread('foggysf1.jpg'); % Read your foggy image here
[~,T,~] = imreducehaze(A); % T is the fog density at each pixel
figure; imshow(T,[]);
Or, if you are looking for quantitative fog removal evaluation descriptor the refer to the link below.

Yes, like I said previously if you are looking for quantitative fog removal evaluation descriptor the refer to the link below.
Using that function you can get a number (Contrast-to-Noise Ratio) for both the foggy and defogged images.
Higher the Contrast-to-Noise Ratio better the defogging efficiency.
