mit dem Titel

    "Image Space Tensor Field Visualization Using a LIC-like Method"


Der Vortrag wird in Deutsch gehalten.

zum Inhalt:

Tensors are of great interest to many applications in engineering
and in medical imaging, but a proper analysis and visualization
remains challenging. Physics-based visualization of tensor fields
has proven to show the main features of symmetric second-order
tensor fields, while still displaying the most important information
of the data, namely the main directions in medical diffusion tensor
data using texture and additional attributes using color-coding, in
a continuous representation. Nevertheless, its application and
usability remains limited due to its computational expensive and
sensitive nature. We introduce a novel approach to compute a
fabric-like texture pattern from tensor fields on arbitrary
non-selfintersecting surfaces that is motivated by image space line
integral convolution (LIC). Our main focus lies on regaining
three-dimensionality of the data under user interaction, such as
rotation and scaling. We employ a multi-pass rendering approach to
estimate proper modification of the LIC noise input texture to
support the three-dimensional perception during user interactions.
