= SYNOPSIS =
i.segment

i.segment [-dwap] group=name output=name [band_suffix=name] threshold=value [radius=value] [hr=value] [method=string] [similarity=string] [minsize=value] [memory=value] [iterations=value] [seeds=name]      [bounds=name] [goodness=name] [--overwrite] [--help] [--verbose] [--quiet] [--ui]

= Flags: =
'''-d''' [[BR]] Use 8 neighbors (3x3 neighborhood) instead of the default 4 neighbors for each pixel

'''-w''' [[BR]] Weighted input, do not perform the default scaling of input raster maps

'''-a''' [[BR]] Use adaptive bandwidth for mean shift [[BR]]  Range (spectral) bandwidth is adapted for each moving window
  
'''-p''' [[BR]] Use progressive bandwidth for mean shift [[BR]] Spatial bandwidth is increased, range (spectral) bandwidth is decreased in each iteration

'''--o''' [[BR]] Allow output files to overwrite existing files

'''--h''' [[BR]] Print usage summary

'''--v''' [[BR]] Verbose module output

'''--q''' [[BR]] Quiet module output

'''--qq''' [[BR]] Super quiet module output

'''--ui''' [[BR]] Force launching GUI dialog

= PARAMETERS =
'''group=name [required]'''
    Name of input imagery or imagery group
'''output=name [required]'''
    Name of output segmentation map
'''threshold=value [required]'''
    Difference threshold between 0 and 1
    Threshold = 0 merges only identical segments; threshold = 1 merges all
'''band_suffix=name'''
    Suffix for output bands with shifted mean value
'''radius=value''' 
    spatial bandwidth in number of cells
'''hr=value'''
    range bandwidth in number of cells
'''method=string'''
    Segmentation method
    Options: region_growing, mean_shift, watershed
'''similarity=string'''
    Similarity calculation method
    Options: euclidean, manhattan
    Default: euclidean
'''minsize=value'''
    Minimum number of cells in a segment
    The final step will merge small segments with their best neighbor
    Options: 1-100000
    Default: 1
'''memory=value'''
    Memory in MB
    Default: 300
'''iterations=value'''
   Maximum number of iterations during the mean shift process
'''seeds=name'''      
    Name for input raster map with starting seeds
'''bounds=name'''
    Name of input bounding/constraining raster map
'''goodness=name'''
    Name for output goodness of fit estimate map
'''--overwrite'''
    Boolean if overtie the existing raster
'''--ui'''
    run with the user interface mode
'''--help'''

'''--verbose'''

'''--quiet'''
