Hello all

I am having some grayscale images that I am trying to make the intensity
gradient uniform accross each image and I am able to do this using
subtract background with rolling ball radius at 50 pixels, light
background checked and using sliding parabloid gives a little better
result but even without that it looks fine. I would like to know the
algorithm behind this or any good book for reference highlighting this
algorithm in detail. Also can someone explain me how this subtract
background is being implemented in ImageJ with the above options selected??

thanks
