  abstract   =  "We introduce a novel approach for identification of objects
                 of interest in volume data. Our approach tries to convey the
                 information contained in two essentially different concepts,
                 the object's boundaries and the narrow solid structures, in
                 an easy and uniform way. The second order derivative
                 operators in directions reaching minimal response are
                 involved for this task. To show the superior performance of
                 our method, we provide a comparison to its main competitor -
                 surface extraction from areas of maximal gradient magnitude.
                 We show that our approach provides the possibility to
                 represent volume data by its subset of a nominal size."
