Purkinje Images: Conveying Different Content for Different Luminance Adaptations in a Single Image
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
Providing multiple meanings in a single piece of art has always been intriguing to both artists and observers. We present Purkinje images, which have different interpretations depending on the luminance adaptation of the ...
Rendering Pearlescent Appearance Based On Paint-Composition Modelling
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
We describe a new approach to modelling pearlescent paints based on decomposing paint layers into stacks of imaginary thin sublayers. The sublayers are chosen so thin that multiple scattering can be considered across ...
Perceptually Guided Corrective Splatting
(Blackwell Publishers Ltd and the Eurographics Association, 2001)
One of the basic difficulties with interactive walkthroughs is the high quality rendering of object surfaces with non-diffuse light scattering characteristics. Since full ray tracing at interactive rates is usually impossible, ...
Lightness Perception in Tone Reproduction for High Dynamic Range Images
(The Eurographics Association and Blackwell Publishing, Inc, 2005)
Temporally Coherent Irradiance Caching for High Quality Animation Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2005)
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 ...
Analysis of Reproducing Real-World Appearance on Displays of Varying Dynamic Range
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
We conduct a series of experiments to investigate the desired properties of a tone mapping operator (TMO) and to design such an operator based on subjective data. We propose a novel approach to the tone mapping problem, ...
Beyond Tone Mapping: Enhanced Depiction of Tone Mapped HDR Images
(The Eurographics Association and Blackwell Publishing, Inc, 2006)
High Dynamic Range (HDR) images capture the full range of luminance present in real world scenes, and unlike Low Dynamic Range (LDR) images, can simultaneously contain detailed information in the deepest of shadows and the ...
State of the Art in Global Illumination for Interactive Applications and High-quality Animations
(Blackwell Publishers, Inc and the Eurographics Association, 2003)
Global illumination algorithms are regarded as computationally intensive. This cost is a practical problem when producing animations or when interactions with complex models are required. Several algorithms have been ...
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 ...
