Homunculus Warping: Conveying Importance Using Self-intersection-free Non-homogeneous Mesh Deformation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Size matters. Human perception most naturally relates relative extent, area or volume to importance, nearness and weight. Reversely, conveying importance of something by depicting it at a different size is a classic artistic ...
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 ...
ShapeGenetics: Using Genetic Algorithms for Procedural Modeling
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In this paper, we show that genetic algorithms (GA) can be used to control the output of procedural modeling algorithms. We propose an efficient way to encode the choices that have to be made during a procedural generation ...
Practical Capture and Reproduction of Phosphorescent Appearance
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
A GPU-Adapted Structure for Unstructured Grids
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
A key advantage of working with structured grids (e.g., images) is the ability to directly tap into the powerful machinery of linear algebra. This is not much so for unstructured grids where intermediate bookkeeping data ...
Minimal Warping: Planning Incremental Novel-view Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Observing that many visual effects (depth-of-field, motion blur, soft shadows, spectral effects) and several sampling modalities (time, stereo or light fields) can be expressed as a sum of many pinhole camera images, we ...
Deep Shading: Convolutional Neural Networks for Screen Space Shading
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In computer vision, convolutional neural networks (CNNs) achieve unprecedented performance for inverse problems where RGB pixel appearance is mapped to attributes such as positions, normals or reflectance. In computer ...
Learning to Predict Localized Distortions in Rendered Images
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
In this work, we present an analysis of feature descriptors for objective image quality assessment. We explore a large space of possible features including components of existing image quality metrics as well as many ...
