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 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,
