You can test the segmentation with these commands:
Creation of a multichannel Red-Green-Blue-Nir image
Apply segmentation
Generate colors instead of labels
Moreover the application can work in two different modes:
Raster mode: allows you to segment a small image and produces a raster where each component of the segmentation is labeled with a unique integer
Vector mode: segment larger images and produce a vector file where each segment of the segmentation is represented by a polygon
OTB also includes a framework to perform tile-wise segmentation of very large images with theoretical guarantees of getting identical results to those without tiling called LSMS_.
OTB in QGis
The same set of OTB applications can also be used from the :menuselection:`Processing --> Toolbox` menu in QGis. The applications are sorted by tag.
Developing with OTB
If you want to use the OTB library and compile your C++ code inside OSGeoLive, you will need to:
Install development package **libotb-dev** and **libqt4-dev** .
Check that **cmake** is installed.
The OTB_DIR location should be found automatically (usually in */usr/lib/x86_64-linux-gnu/cmake/OTB-...*). In your CMake configuration, you should link the libraries in the variable OTB_LIBRARIES.
More information can be found in the Software Guide.

OTB Software Guide
The main source of information is the OTB Software Guide. This is a comprehensive guide which comprises about 600 pages, detailing the steps to install OTB and use it. Most of the classes available are heavily illustrated with results from real remote sensing processing.
OTB CookBook
A guide for OTB-Applications and Monteverdi dedicated for non-developers is also available.This guide is composed of a brief tour of of OTB-Applications and Monteverdi, followed by a set of recipes to perform usual remote sensing tasks with both tools.
