 == Segmentation of single band panchromatic image ==
+
 This example uses the panchromatic image inluded in the NC sample dataset.
 Set up an imagery gourp:
 {{{i.group group=singleband input=lsat7_2002_80}}}
 
+Set the segmentation region, the first testing case will be the full image.
 {{{g.region raster=lsat7_2002_80 -p}}}
 
+Firstly test the region with least input arguments.
 {{{i.segment --o group=singleband  output=lsat7_2002_80_MM_min1 method=mean_shift thresh=0.01}}}

+Compare with the original image, there are many samll segmentations showing because min_seg_size has been set to 1.
+Then zoom in to a smaller region and compare with the original image.
