Flat fields to correct for uneven illumination -- has anyone tried this?
Posted: 16 Apr 2017, 22:45
There is a well known process -- flat fielding -- that is used to correct for uneven illumination in images in scientific and astronomical images. See here:

I'm wondering if anyone has tried this method to eliminate or reduce illumination gradients that many lighting configurations? I'm sure it is a very compute intensive process but is something that could be useful when it's important to get evenly lit images and lighting is not optimal.
