I have 3 formula, (P and S is the same picture that taken with different method)

1. P/S
2. P/(P+S)
3. |P-S|/|P+S|

Image P

Image S

and with one of these formula the result will become like this :

how to implemet these formula in c++ ?

if i`m using

subtract(P, S, min); 
add(P, S, plus);`

is that same as P-S and P+S, and how to devided P with S ?
