<p>Oh one more small thing comes to my mind:<br>
<br>
In the minimal example skimage code that I gave, I included two
test files: testImage.png and testImageTiny.png<br>
The *Tiny.png strangely does not show the memory blowup at all. I
don't understand this behavior at all, but included anyway. Maybe
it helps for finding out more about the problem.<br>
</p>
<p>> FWIW, binary images are stored as ubyte, so 1 *byte* per
pixel.<br>
<br>
Sounds strange. Have to google about this. Thanks for the Info,
anyway! :)<br>

a 1.2GB file stops due to memory problems already in
skimage.morphology.remove_small_objects() even if the major
