we will use the command line tool, otbcli_Segmentation to segment part of a
LISS-III scene and demonstrate the impact of the different segmentation algorithms
(meanshift, edison); additional segmentation algorithms are included in the module
that include: cc, watershed and mprofiles. The segmentation results can either be
output as a raster or vector dataset. First, we present the module documentation that
includes the different flags and options.
