  abstract =   "The paper presents an approach to visually enhance
               representations of volume data as a means to improve volume
               visualization. Direct volume rendering is employed to
               represent several volume data sets, using the popular Ray
               Casting algorithm. The result is rendered to a texture via
               an off-screen framebuffer, which then goes through a
               post-rendering processing stage. This stage involves the
               application of image enhancement techniques such as the use
               of spatial filters, to produce clearer, sharper, and less
               noisy images of the rendered volume. Depending on the
               specifics of the volumetric data set, post-rendering
               enhancement may bring forth more relevant visual information
               or otherwise improve the overall quality of the resulting
               images.",
