i am getting values using

imshow strip1.tiff
vals = impixel

then i have to substitute the values of R , B , G in this equation

Ar = -log (Rs/ Rb)
Ag = -log (Gs/ Gb)
Ab = -log (Bs/ Bb)

and plot graph for RGB in one graph itself.

What are "Rs", "Gs", "Bs", "Rb", "Gb", "Bb" ?

R = vals(:,1);
G = vals(:,2);
B = vals(:,3);
