Hi,

> What colleagues here have also noticed is that between the versions (but I can't remember if it was 7.0 vs 7.3 or 7.2 vs 7.3) quite different thresholds were needed to reach similar segmentation results. In 7.3 reasonable thresholds are often an order of magnitude lower, i.e. 0.001 instead of 0.01...

this wasn't my case. I am getting slightly different results in G72

i.segment complete. Number of segments created: 4367082
(Sun Dec  4 09:42:19 2016) Command finished (3 min 36 sec)

and G73

i.segment complete. Number of segments created: 4359666
(Mon Dec  5 13:45:41 2016) Command finished (4 min 44 sec)

But not so much. Segmentation process is also a little bit slower in
this case (and takes more iterations: 8->14). Ma
