Tutorial Step 6: region growing does not display results
Closed, WontfixPublic


When executing the step 6 of the tutorial it does not show the results from the region growing. This was tested by setting one and several seed points in a version of the software compiled with Visual Studio (release and debug).

There seem to be some computations going on, since the ui is blocked for some time and there is logging output. However, after the ui is accessable again, nothing new is displayed.

Here is the console output:

I could not reproduce this bug. Seems to be fixed in the meantime.

Sebastian, could you please try to reproduce this bug on your linux machine?

Sebastian reported this bug from a windows machine, so I will close this bug.

Hello, I ran into the same problem as you when running tutorial Step6. How did you solve it?

floca edited projects, added Missing Info, MITK (v2021.02); removed MITK.

Plesae, could you add some more information (which version?, which OS?, is it reproducible with different images? Preferably an image that can be shared. E.G. something from the MITK-Data repository)

I tested Tutorial Step 6 with Windows (presumably what the OP used) and Pic3D (see task description: C:\ws\MITK\bin\CMakeExternals\Source\MITK-Data\Pic3D.nrrd).
Depending on the threshold values I used I was either able to get a segmentation mask or the UI froze for a short time and nothing happened.
However, I did not receive any log output related to GPU, OpenGL or the like.

It is to mention that the region growing does not work (show any results) with the default thresholds (-1000 - -400). Maybe this is the problem of the OP.
After I used the default thresholds with a single seed-point I added some more seed-points and then I got the following error:

So whatever @Kevin experienced, I could somehow reproduce the original problem.

Steps to reproduce:

  • start tutorial step 6 with \MITK-Data\Pic3D.nrrd
  • set seed-point and hit start region growing (with default threshold values (-1000 - -400))
  • see how nothing happens after the app froze for a few seconds
  • set another seed-point

Another way to reproduce:

  • start tutorial step 6 with \MITK-Data\Pic3D.nrrd
  • hit start region growing (with default threshold values / no seed-point)
  • see how nothing happens after the app froze for a few seconds
  • scroll in one of the render windows

I also tested 4D data and the tutorial crashed (see T27541).
