Sky Based Light Metering for High Dynamic Range Images
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Image calibration requires both linearization of pixel values and scaling so that values in the image correspond to real-world luminances. In this paper we focus on the latter and rather than rely on camera characterization, ...
Real-Time Symmetry-Preserving Deformation
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
In this paper, we address the problem of structure-aware shape deformation: We specifically consider deformations that preserve symmetries of the shape being edited. While this is an elegant approach for obtaining plausible ...
Perceptually-motivated Stereoscopic Film Grain
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Independent management of film grain in each view of a stereoscopic video can lead to visual discomfort. The existing alternative is to project the grain onto the scene geometry. Such grain, however, looks unnatural, changes ...
Interactive Motion Mapping for Real-time Character Control
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Abstract It is now possible to capture the 3D motion of the human body on consumer hardware and to puppet in real time skeleton-based virtual characters. However, many characters do not have humanoid skeletons. Characters ...
Manipulating Refractive and Reflective Binocular Disparity
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Presenting stereoscopic content on 3D displays is a challenging task, usually requiring manual adjustments. A number of techniques have been developed to aid this process, but they account for binocular disparity of surfaces ...
Spectral Ray Differentials
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Light refracted by a dispersive interface leads to beautifully colored patterns that can be rendered faithfully with spectral Monte-Carlo methods. Regrettably, results often suffer from chromatic noise or banding, requiring ...
Extended Branch Decomposition Graphs: Structural Comparison of Scalar Data
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
We present a method to find repeating topological structures in scalar data sets. More precisely, we compare all subtrees of two merge trees against each other - in an efficient manner exploiting redundancy. This provides ...
Sets of Globally Optimal Stream Surfaces for Flow Visualization
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Stream surfaces are a well-studied and widely used tool for the visualization of 3D flow fields. Usually, stream surface seeding is carried out manually in time-consuming trial and error procedures. Only recently automatic ...
