Apparatus and method for semi-automatic classification of volume data

摘要

An apparatus for semiautomatic classification of volume data provides the ability to generate visually significant representations of the important regions of the data set. The representations may be indicated by opacity or color changes, for example. The apparatus comprises programming to compute a two-dimensional (2D) histogram over a volume of scalar values, f, versus edge values edge( ). A common edge value is the gradient magnitude, edge ( )=|∇f|.
