Exactly Joachim, our images have an irregular surface to be measured the
volume after segmentation of the background. And in addition to that we have
always more than one unique cell per area, and thses cells must be baseline
filtered prior calculations of volume or other analyses of measurable
parameters. We can now see the image, but we can not display the 3D volume
or measure it...
