Dear Paul,
Within ImageJ, when you press the key "l" the command finder window will appear.
Within it you can start to write "brightness" but already with "brig" i get as only choice the Brightness/Contrast... tool.
And when you select it and press the "Source" button you will directly be linked to the following adress:
https://imagej.nih.gov/ij/source/ij/plugin/frame/ContrastAdjuster.java
and looking a little bit within the ciode you can find that it is the following method that is doing the job:
void autoAdjust(ImagePlus imp, ImageProcessor ip)
My best regards,
Philippe

Hi,
What is the algorithm of B&C Auto function. How are the Minimum and Maximum values calculated exactly when Auto button is presses. I am trying to replicate the calculation in Python.
Thanks.

Best regards,

Paul
