[GRASS-dev] Implementation of the High Pass Filter Additive Fusion technique (i.fusion.hpf)

[Nick Ves]

The HPF algorithm about the histrogram matching states "Stretch the
new multispectral image to match the mean and standard deviation of
the
original (input) multispectral image"

In that context why it is wrong to do  :

Ouput <- output/sddev(output)*sddev(input)

Output <- Output - mean(output) + mean(input)
