[IP2-1-3-1] Gram-Schmidt pan-sharpening

Gram-Schmidt is a pan-sharpening method that has been invented by Laben and Brover in 1998 and patented by Eastman Kodak. It makes use of the Gram-Schmidt orthogonalization to decorrelate the spectral bands (panchromatic, red, green, blue, etc.) and transform them into one multidimensional vector.
