Mmmmh,
I was a bit too fast for responding. If you want to average objects
without average the background, not only paste non-zero pixels, the
simpliest way is to extract the objects.
If img1 is the destination image and img2 the image to be blended, I
will threshold my objects (Image>Adjust>Threshold) in img2, then create
a selection (Edit>Selection>create selection) then copy/paste these img2
objects on img1 in blend mode.
Other ways to proceed are welcome ...
