Detailed Description

First PCA on Covariance matrix of Rgb Pixels.

Author:

Purpose:        PCA on covariance matrix of color RGB pixels allows to compute a fast separation
                of PCA components.

                Computation of the covariance is reduced, because we are not dealing with large number of channels.
                Also, we have the advantage, that the ordered PCAs can be evaluated quickly.
                The strongest PCA holds the most information.

                A very good public routine to tri-diagonalize a real symmetric matrix uses Householder's method.
