 Hi,

 I tested the new i.superpixels.slic add-on on the North Carolina dataset.
 It is very fast and interesting.

 Unfortunately, when reaching a region of more than 500x500 pixels (it is
 what I've found), the add-on crashes.

 Here after the command I used

 OK:

 g.remove -f type=group name=ortho

 i.group  group=ortho input=ortho_2001_t792_1m

 g.region raster=ortho_2001_t792_1m n=219956 s=219456 e=637533 w=637033
 rows=500 cols=500

 g.region -p

 i.superpixels.slic --overwrite group=ortho k=500 output=slic_segment


 Failing:

 g.remove -f type=group name=ortho

 i.group  group=ortho input=ortho_2001_t792_1m

 g.region raster=ortho_2001_t792_1m n=219966 s=219456 e=637543 w=637033
 rows=510 cols=510

 g.region -p

 i.superpixels.slic --overwrite group=ortho k=500 output=slic_segment


 A pop-up window appears with an "APPCRASH" message saying that GRASS 7
 stops working.


 FYI: my PC runs with an Intel core i5-3570 CPU (64 bits) (3.4Ghz) and 32Go
 RAM
