"Interactive GPU-based Visualization of Scalar Data with
Gaussian Distributed Uncertainty".<br>
<br>
Abstract:<br>
<br>
We present a GPU-based approach to visualize samples of normally<br>
distributed uncertain, three-dimensional scalar data. Our
approach uses a<br>
mathematically sound interpolation scheme, i.e., Gaussian
process<br>
regression. The focus of this work is to demonstrate, that
GP-regression<br>
can be a used for interpolation in practice, despite the high
computational<br>
costs. The potential of our method is demonstrated by an
interactive volume<br>
rendering of three-dimensional data, where the gradient
estimation is<br>
directly computed by the field function without the need of
additional<br>
sample points of the underlying data. We illustrate our method
using<br>
three-dimensional data sets of the medical research domain.<br>
