Differences in the multi-information reduction between various decorrelation transforms (SYM, PCA, ICA) relative to a random decorrelation transform (RND) compared to the multi-information reduction achieved with the random decorrelation transform relative to the original pixel basis (RND-PIX). The absolute multi-information reduction is given in bits/component on the left hand side. The right hand side shows how much more the special decorrelation transforms SYM, PCA and ICA can reduce the multi-information relative to the random (RND) one.
