Hi Karsten,
Here is one solution using the the ShapeLogic plugin.
I assume that the image's color coding is using in inverted lookup
table, otherwise you have to change a few things.
Do an Image Calculation Or between you original image and the mask
that is in the top center of your image link.
Now you have the original image with the background being black and
the regions separated by thin black lines.
Call the ShapeLogic>> RGB Color Particle Analyzer
With these settings:
Max distance: 0
Min pixels: 0
Max pixels: 100000000
RGB R: 0
RGB G: 0
RGB B / Gray: 255
Background: checked
CountOnly: unchecked
ToMask: unchecked
DisplayInternalInfo: unchecked
