Good day Josh,

you've realized the main problem with threshold-based binarization...

Although there are equalization methods to help with uneven signals,
they won't do any magic.

Try to find a solution without thresholds:
Perhaps classification may help or a more adequate way of image
acquisition (often not considered!).

In any case, without seeing a _typical_ example image, it is difficult
to give more helpful advice.

Best

Herbie
