Paper Abstract

An algorithm is presented for rendering of volumetric data sets. The aim of the algorithm is to maximize the image variance in a volumetric rendering where a three-dimensional data set is projected onto a view plane through the perspective mapping. The pixel values in the rendered image are associated with a variable-sized attribute vector extracted along a line in the volumetric data set. Several algorithms are presented for transforming this variable-sized attribute vector into a fixed-sized attribute vector. The fixed-sized attribute vectors provide a multi-spectral image representation which is processed with the Karhunen-Loeve transformation in order to separate the information content into orthogonal components and ordered according to the associated eigenvalues. The components in the Karhunen-Loeve transform can be displayed individually as intensity images or three components can be selected and mapped into a coloring scheme such as the HSV color model.
