How to superpose gray scale JPG files, getting the darkest pixel?

[samz]

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.

Go to File->Scripts->Statistics. Set Stack Mode to Minimum, Browse for your files and press OK.

Thank you so much SCTRWD,
The result of your solution is exactly what I would to get.

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.

Regards.

Glad to help. Just beware it works only on gray-scale images. For full color images you can record simple action: create new document, open image, copy, paste to current image, set Mode to Darken, Merge layers. Run this in a batch mode on your files.

IMHO, this works much faster for any images: full color or gray-scale ones. And quite easy on memory and CPU usage.
