Donny,
either you have a plain image, just with your background, then you can
perform an a priori shading correction, otherwise you can use an a
posteriori corrector...
check this out:

BTW: I have the mentioned a posteriori shading corrector from the
University of Reims - the Professor there is now retired so he took his
page off the web, unfortunately all the plugins are gone as well; for me
it works extremely well. if you want to test this particular corrector,
let me know and I will mail you the jar file.
Best,
Johannes
