Modeling Luminance Perception at Absolute Threshold
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
When human luminance perception operates close to its absolute threshold, i. e., the lowest perceivable absolute values, appearance changes substantially compared to common photopic or scotopic vision. In particular, most ...
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 ...
Pre-convolved Radiance Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The incident indirect light over a range of image pixels is often coherent. Two common approaches to exploit this inter-pixel coherence to improve rendering performance are Irradiance Caching and Radiance Caching. Both ...
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 ...
Microtiles: Extracting Building Blocks from Correspondences
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this paper, we develop a theoretical framework for characterizing shapes by building blocks. We address two questions: First, how do shape correspondences induce building blocks? For this, we introduce a new representation ...
Optimizing Disparity for Motion in Depth
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Beyond the careful design of stereo acquisition equipment and rendering algorithms, disparity post-processing has recently received much attention, where one of the key tasks is to compress the originally large disparity ...
Enhancement of Bright Video Features for HDR Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
To utilize the full potential of new high dynamic range (HDR) displays, a system for the enhancement of bright luminous objects in video sequences is proposed. The system classifies clipped (saturated) regions as lights, ...
Combining Confocal Imaging and Descattering
(The Eurographics Association and Blackwell Publishing Ltd, 2008)
In translucent objects, light paths are affected by multiple scattering, which is polluting any observation. Confocal imaging reduces the influence of such global illumination effects by carefully focusing illumination and ...
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 ...
Learning a Self-supervised Tone Mapping Operator via Feature Contrast Masking Loss
(The Eurographics Association and John Wiley & Sons Ltd., 2022)
High Dynamic Range (HDR) content is becoming ubiquitous due to the rapid development of capture technologies. Nevertheless, the dynamic range of common display devices is still limited, therefore tone mapping (TM) remains ...
