Hi Benoit,

With the option t=1, the algorithm uses 
NeighborhoodConnectedImageFilter:
https://itk.org/Doxygen/html/classitk_1_1NeighborhoodConnectedImageFilter.html

If I understand correctly the documentation, to be labeled, a voxel has 
to be connected to the seed AND all its neighbor voxels (defined by the 
radius option) also.
So If your output correspond to the seed, maybe your radius (-r 10) is 
too high. By default it's 1 but you can try with 0 and other value 
between 0 and 10.

Regards
Thomas
