[GRASS-user] Sky-view Factor and GeoTiff Histogram equalization (stretch)

[Adrian Kirilov]

     Hello to the GRASS users,

     Does anybody know how to equalize, or stretch, the histogram of a
raster? The last represents Sky-view Factor based on a DEM model. It is
well-known visualization technique when looking for archaeological
structures.

     I have to do *minimum-maximum stretch of the histogram with saturation
of minimum*. How to do this in GRASS? Any help will be highly appreciated!
Thank you!
