abstract = {The ultimate goal of many applications of augmented reality is to
immerse the user into the augmented scene, which is enriched with
virtual models. In order to achieve this immersion, it is
necessary to create the visual impression that the graphical
objects are a natural part of the user's environment. Producing
this effect with conventional computer graphics algorithms is a
complex task. Various rendering artifacts in the three-dimensional
graphics create a noticeable visual discrepancy between the real
background image and virtual objects. We have recently proposed a
novel approach to generating an augmented video stream. With this
new method, the output images are a non-photorealistic
reproduction of the augmented environment. Special stylization
methods are applied to both the background camera image and the
virtual objects. This way the visual realism of both the graphical
foreground and the real background image is reduced, so that they
are less distinguishable from each other. Here, we present a new
method for the cartoon-like stylization of augmented reality
images, which uses a novel post-processing filter for cartoon-like
color segmentation and high-contrast silhouettes. In order to make
a fast postprocessing of rendered images possible, the
programmability of modern graphics hardware is exploited. We
describe an implementation of the algorithm using the OpenGL
Shading Language. The system is capable of generating a stylized
augmented video stream of high visual quality at real-time frame
rates. As an example application, we demonstrate the visualization
of dinosaur bone datasets in stylized augmented reality.},
