Are you talking about distance fog, like this?
Fog is basically a decrease in contrast or linear blending with a solid color such as blue-gray, but the amount of blending varies according to the distance to the objects in the scene. That's not something you can easily do without depth info.

nice. from there you can start counting the red pixels based on the RGB function, image(x,y,1:3)... where x and y is their coordinates while 1:3 will tell the RED, GREEN and BLUE values.
since you want the RED pixels, then you can select your RED threshold values and count those pixels.
count = 0;
