Hi
Thanks for your ideas, my 3D image comes from a micro CT, so the difference
on the materials is given by its density.
I used Otsu method as my global segmentation, but I want a local
segmentation.
My problem was using the plugin marker-controlled watershed which was (at
least for me) not clear how to create the marker but finally I succeed.
what I did was:
The marker is an image the global segmented image but with the boundary
borders voxels=0, in order to have a value 0 in the borders I binarized the
gradient and subtract it to the global segmented image.
With this marker and the gradient of my image the plugin works well.
