<p>Hi all!<br></p><p>Image groups created using <code>i.group</code> in
GRASS GIS are used to bundle band raster files to facilitate
classification processes. Other than that under what scenarios it can be
used?</p>
<p>A journal article <a href="http://hera.ugr.es/doi/15003954.pdf" rel="nofollow">Computing geostatistical image texture for remotely sensed data classification - PDF</a>
mentions about using different band/result combinations for checking
improvements in accuracy. The authors there use a custom code to
generate texture layers and finally use different combinations of
texture layers and bands to check the improvements in accuracy. The
texture layers are images which are pixel wise manipulated images
obtained using a custom code applied on Principal Components of LANDSAT
Images. They use several combinations like bands+univariate texture
layers, bands+fractal dimension layers and many more. For such a case,
can <code>i.group</code> be used? If not what module of GRASS would be suitable for that?</p>
