Perceptual Evaluation of Color-to-Grayscale Image Conversions
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Color images often have to be converted to grayscale for reproduction, artistic purposes, or for subsequent processing. Methods performing the conversion of color images to grayscale aim to retain as much information about ... -
Perceptual Evaluation of Common Line Variables for Displaying Uncertainty on Molecular Surfaces
(The Eurographics Association, 2022)Data are often subject to some degree of uncertainty, whether aleatory or epistemic. This applies both to experimental data acquired with sensors as well as to simulation data. Displaying these data and their uncertainty ... -
Perceptual evaluation of footskate cleanup
(The Eurographics Association, 2011)When animating virtual humans for real-time applications such as games and virtual reality, animation systems often have to edit motions in order to be responsive. In many cases, contacts between the feet and the ground ... -
Perceptual Evaluation of Ghosted View Techniques for the Exploration of Vascular Structures and Embedded Flow
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents three controlled perceptual studies investigating the visualization of the cerebral aneurysm anatomy with embedded flow visualization. We evaluate and compare the common semitransparent visualization ... -
Perceptual Evaluation of Impostor Representations for Virtual Humans and Buildings
(The Eurographics Association and Blackwell Publishing, Inc, 2005) -
Perceptual Evaluation of LOD Clothing for Virtual Humans
(The Eurographics Association, 2006)Recent developments in crowd simulation have allowed thousands of characters to be rendered in real-time. Usually this is achieved through the use of Level of Detail (LOD) models for the individuals in the crowd. Perceptual ... -
Perceptual Global Illumination Cancellation in Complex Projection Environments
(The Eurographics Association and Blackwell Publishing Ltd., 2011)The unintentional scattering of light between neighboring surfaces in complex projection environments increases the brightness and decreases the contrast, disrupting the appearance of the desired imagery. To achieve ... -
Perceptual Level of Detail for Efficient Ray Tracing of Complex Scenes
(The Eurographics Association, 2005)Rendering complex scenes in real time remains one of the major challenges in computer graphics. Recent research in perceptual rendering algorithms and level of detail techniques have shown that, by exploiting knowledge of ... -
Perceptual Metrics for Static and Dynamic Triangle Meshes
(The Eurographics Association and Blackwell Publishing Ltd., 2013)Almost all mesh processing procedures cause some more or less visible changes in the appearance of objects represented by polygonal meshes. In many cases, such as mesh watermarking, simplification or lossy compression, the ... -
Perceptual Metrics for Static and Dynamic Triangle Meshes
(The Eurographics Association, 2012)Almost all mesh processing procedures cause some more or less visible changes in the appearance of objects represented by polygonal meshes. In many cases, such as mesh watermarking, simplification or lossy compression, the ... -
Perceptual modeling for stereoscopic 3D
(2016-11-04)Virtual and Augmented Reality applications typically rely on both stereoscopic presentation and involve intensive object and observer motion. A combination of high dynamic range and stereoscopic capabilities become popular ... -
Perceptual Principles and Computer Graphics
(Blackwell Publishers Ltd and the Eurographics Association, 2000)Now that technology allows us to present photorealistic animations of scenically lit objects acting in real-time, the problem of computer graphics has changed from making displays recognisable, to ensuring that users notice ... -
Perceptual Principles and Computer Graphics

Perceptual Principles and Computer Graphics
(Eurographics Association, 1999)Until comparatively recently, the major problems in computer display technology were caused by the difficulty of making anything recognisable at all. Eighty character-width displays, with eight or nine brilliant green lines ... -
Perceptual Quality Assessment of NeRF and Neural View Synthesis Methods for Front-Facing Views
(The Eurographics Association and John Wiley & Sons Ltd., 2024)Neural view synthesis (NVS) is one of the most successful techniques for synthesizing free viewpoint videos, capable of achieving high fidelity from only a sparse set of captured images. This success has led to many variants ... -
Perceptual Quality of BRDF Approximations: Dataset and Metrics
(The Eurographics Association and John Wiley & Sons Ltd., 2021)Bidirectional Reflectance Distribution Functions (BRDFs) are pivotal to the perceived realism in image synthesis. While measured BRDF datasets are available, reflectance functions are most of the time approximated by ... -
Perceptual Reparameterization of Material Properties
(The Eurographics Association, 2007)The recent increase in both the range and the subtlety of computer graphics techniques has greatly expanded the possibilities for synthesizing images. In many cases, however, the relationship between the parameters of an ... -
A Perceptual Shape Loss for Monocular 3D Face Reconstruction
(The Eurographics Association and John Wiley & Sons Ltd., 2023)Monocular 3D face reconstruction is a wide-spread topic, and existing approaches tackle the problem either through fast neural network inference or offline iterative reconstruction of face geometry. In either case ... -
Perceptually Adaptive Graphics
(Eurographics Association, 2004)In recent years, the Graphics community has come to realise the importance of taking human perception into account when striving for realism in images, animations and Virtual Environments. In May 2001, a EUROGRAPHICS/ ... -
Perceptually Based Afterimage Synthesis
(The Eurographics Association, 2012)Afterimages comprise a common, recurring perceptual phenomenon experienced in a daily-basis. Afterimages are best realized when staring at some high intensity light source (i.e., a light bulb) and then shifting the ocular ...
