[GRASS-user] GRASS Image Groups applications

[Chethan S.]

Hi all!

Image groups created using i.group in GRASS GIS are used to bundle band
raster files to facilitate classification processes. Other than that under
what scenarios it can be used?

A journal article Computing geostatistical image texture for remotely sensed
data classification - PDF <http://hera.ugr.es/doi/15003954.pdf> 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 i.group be used? If not what module of GRASS
would be suitable for that?
Thanks and regards,

Chethan S.
