Disclosed is a method for enabling easy characterization, storage and retrieval of multi-dimensional data structures involving use of a translation, rotation and scaling invariant index which results from concatenating a series of Eigenvalue calculation mediated index elements determined at a plurality of hierarchical data depth levels by characterizing spatial first and second central moment calculations, optionally including pre-selection of pixels in data structures which demonstrate significant intensity and/or color gradients with respect to surrounding pixels. Preferred characterizing vector(s) consist of typically orthogonally specific frequency integer counts of said pre-selected pixels, as well as spatial data structure first central monent value(s), and non-degenerate parameters determined from Eigenvalues derived from second central moments.
