I tried i.segment to perform segmentation on a part of UAV orthophoto image, but this always results in stripe-like rectangle segments which I do not expect. Could anyone figure out what happens?
Please let me note that r.info returns the size of this image as 6075 rows and 4525 columns, but g.region i -p returns only 86 rows and 7 columns.
The settings for image segmentation were as follows:
input: 3 bands (RGB) of raster maps threshold: 0.01 minimum # of segment: 1 max. iteration: 100 others: default
r.info ...for each of the three bands. Also
i.group -l group=<your_image_group>. And last, the full
i.segmentcommand that you ran.
