  abstract = {We present a simple and efficient method to enhance the perceptual
              quality of images that contain depth information. Similar to an
              unsharp mask, the difference between the original depth buffer
              content and a low-pass filtered copy is utilized to determine
              information about spatially important areas in a scene. Based on
              this information we locally enhance the contrast, color, and other
              parameters of the image. Our technique aims at improving the
              perception of complex scenes by introducing additional depth cues.
              The idea is motivated by artwork and findings in the field of
              neurology, and can be applied to images of any kind, ranging from
              complex landscape data and technical artifacts, to volume
              rendering, photograph, and video with depth information.},
