[GRASS-user] Inverse PCA in GRASS

[Venkatesh Raghavan]

Dear All,

Commonly described method for image fusion in
in several publications involves inverse PCA transform
to get the new R,G,B bands of multispectral image from
the principle components.

Does any of you know a script or an algorithm to implement
inverse PCA in GRASS?

Thanks in advance.
