    abstract     = "A new scheme is proposed for handling initial exploratory analyses of multivariate image data. The method  is invariant to linear transformations of the original data and is useful for data fusion of multisource measurements. The scheme includes dimensionality reduction followed by unsupervised clustering of the data. A transformation is proposed which maximizes autocorrelation by projection onto subspaces with signal-to-noise ratio dependent variance. We apply the traditional fuzzy c-means algorithm and introduce two additional  memberships enhancing the textural awareness of the algorithm. Cluster validation is performed by examining the partition density of the segmentations as a function of the number of classes applied. Results are presented for a synthetic {2-}band noise degenerated image and for an {8-}band SeaWiFS scene."
