Hello,
Let's file0.jpg, ..., file99.jpg, 100 gray scale JPG files.
Let's f0(m;n) the pixel (m;n) of image file0.jpg.

How to superpose all those files in one file (superpose.jpg) in this way:
superpose(m;n) = DarkestPixelOf(f0(m;n), ..., f99(m;n))

Using any software.
Using a batch processing method (of course).

Thanks Regards.

The goal of this superposition is to see the common empty/white areas I can crop using a script applied on all (203) file./images.


Thanks.
