This update brings several improvements in the code of the plugin.
In particular, Orfeo Toolbox is no longer required for the plugin. All the functions that required Orfeo Toolbox have been replaced.
The ROI region growing is performed using GDAL, Numpy and SciPy, which replace the Orfeo Toolbox segmentation. This improves the elaboration speed, and ROIs are created almost instantly.
Moreover, this update allows for simpler installation of the plugin in Windows 64 bit (Orfeo Toolbox is not available in OSGEO4W for Windows 64 bit) and several Linux distribution such as Debian (Orfeo Toolbox is not available in the official repositories). See here for more information about the installation.
The updated Semi-Automatic Classification Plugin is already available through the QGIS repository, or can be downloaded here.
