I am trying to perform segmentation from Orfeo Toolbox (QGIS last version 2.2), whenever I try to use the toolbox, I get the following message:
Oooops! The following output layers could not be open
Output labeled image: D:/ERDAS_examples/Sardegna 1954/segmnentation.tif
The above files could not be opened, which probably indicates that they were not correctly produced by the executed algorithm
Checking the log information might help you see why those layers were not created as expected
The same when I try to use SAGA toolbox:
Missing dependency.This algorithm cannot be run :-(
This algorithm requires SAGA to be run.Unfortunately, it seems that SAGA is not installed in your system, or it is not correctly configured to be used from QGI,
Click here to know more about how to install and configure SAGA to be used with QGIS
How do I solve this?
