We did ours using a gamma adjustment for brightness. Actually, our color
scientist gave me the matlab files and I implement a BuffereImageOp contrast/brightness
adjustment. I probably can't give you that code since Xerox owns it, but
if you look at gamma and sigmoid functions, you'll get there.

Can anyone suggest a source or an algorithm for brightness and contrast adjustments

I’m assuming rgb is appropriate here…
I have implemented some code using LUT tables but I haven’t come across a
mathematical description.
