2D region growing tool fails for low intensity regions
Open, HighPublic

Description

The 2D region growing tool fails if you try and start it from a seed point inside a low intensity image region like the lung e.g. in MRI. Expected behaviour is that a region contour is displayed that changes if the threshold is adjusted via up or down mouse movement. Nothing happens instead. Priority set to high since it makes MITK unapplicable for commonly encountered scenarios like manual segmentation e.g. of said low intensity regions.

Is there some rough estimate when this bug was introduced?

@norajitr or someone else: is there an example image in MITK Data to show this behavior?
@norajitr do you know when this stopped working?

do you know when this stopped working?

The error was first noticed recently while working with clinical partners on MRI lung data from the NAKO. I checked the old installer from 2015, where it also did not work.

or someone else: is there an example image in MITK Data to show this behavior?

I could not find a suitable lung example in MITK Data. I checked on two old lung MRI datasets in the department, where the problem did not occur.

Does the MITK team have access rights on the NAKO dataset? Then I would suggest an example from there.

Would be great if you could point me to an example.
