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.
