-=NAME=
+= NAME =
 i.segment mean shift algorithm - Identifies segments (objects) from imagery data using mean shift algorithm.
+
+= KEYWORDS = 
+ [https://grass.osgeo.org/grass73/manuals/imagery.html imagery], [https://grass.osgeo.org/grass73/manuals/topic_segmentation.html segmentation], 
+
+= 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
