another image problem


Let's say you have a picture of two overlapping graphs.

You don't have the equations that generated them. but you know the
graphs is relatively accurate. for example,

Now... let's say you wanted to find the area under curve for both
curves (blue and green) between certain x values...

for example, 425nm <= x <= 475nm , and then 500nm <= x <= 550nm, and
then 525nm <= x <= 575nm.

is this doable in Mathematica? 

thanks In advance for any thoughts.
