error during ITK Watershed Auto Seeded
Issue #8
resolved
Hello,
I'm trying to segment arabidopsis root, and while applying ITK Watershed Auto Seeded filter I get the next error message (please see the attached file).
What am I doing wrong and how can I resolve it?
Thank you in advance, Yulia

Increasing blur solved the problem.

Yes, this can happen if you have too much noise. The reason is: the watershed algorithm will label each voxel with a unique number identifying which cell it is a part of. In LithoGraphX, every voxel can store a number from 0 to 65535. So if the Watershed finds more than 65534 cells (0 is for the outside), it will run out of unique numbers and display the error you see.
Depending on the image you have a few choices:
The main advantage of the new "Sieve" algorithm (available on version 1.1.6 or later) is the conservation of the shape of larger objects, where the Gaussian blur will tend to smooth everything.
