Closed, ResolvedPublic
Actions

Description

To reproduce:
Load US4DCyl or Pic3D
+ Go to the segmentation view
+ Choose dynamic segmentation
+ Select Watershed Tool
+ turn the threshold high (0.85)
+ Press preview
= Crash ….

ERROR: Watershed Filter Error: itk::ERROR: itk::watershed::SegmentTreeGenerator::MergeSegments:: An unexpected and fatal error has occurred. This is probably the result of overthresholding of the input image.

It is rooted in an known unfixed error in itk: https://discourse.itk.org/t/crash-in-watershedimagefilter/2428

Currently we can only hatch the error with try catch and try to minimize the chance by limiting thresholt to an unrisky value range. Will do so in D391.
