#3705 closed defect (duplicate)

i.segment produces empty output

Reported by: martinl Owned by: grass-dev@…
Priority: normal Milestone: 7.4.4
Component: Imagery Version: unspecified
Keywords: i.segment, empty output Cc:
CPU: Unspecified Platform: Unspecified

Description (last modified by martinl)

From G74:i.segment manual: 

i.group group=ortho_group input=ortho_2001_t792_1m@PERMANENT
g.region -p raster=ortho_2001_t792_1m n=220446 s=220075 e=639151 w=638592
i.segment group=ortho_group output=ortho_segs_l1 threshold=0.02

The last command says 

i.segment complete. Number of segments created: 119346

But output raster map is empty: 

r.info -r ortho_segs_l1
min=NULL
max=NULL

All GRASS versions (7.7, 7.6, 7.4) seems to be affected.
