A Computational Model of Afterimages
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
Afterimages are optical illusions, particularly well perceived when fixating an image for an extended period of time and then looking at a neutral background, where an inverted copy of the original stimulus appears. The ...
The Online Anatomical Human: Web-based Anatomy Education
(The Eurographics Association, 2016)
The Online Anatomical Human (OAH) is a web-based viewer for studying anatomy. It is based on real human anatomy and incorporates medical image data in linked 2D and 3D views that students can freely interact with. Our ...
Perceptually-motivated Real-time Temporal Upsampling of 3D Content for High-refresh-rate Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)
High-refresh-rate displays (e. g., 120 Hz) have recently become available on the consumer market and quickly gain on popularity. One of their aims is to reduce the perceived blur created by moving objects that are tracked ...
Voxel DAGs and Multiresolution Hierarchies: From Large-Scale Scenes to Pre-computed Shadows
(The Eurographics Association, 2018)
In this tutorial, we discuss voxel DAGs and multiresolution hierarchies, which are representations that can encode large volumes of data very efficiently. Despite a significant compression ration, an advantage of these ...
Perceptual Depth Compression for Stereo Applications
(The Eurographics Association and John Wiley and Sons Ltd., 2014)
Conventional depth video compression uses video codecs designed for color images. Given the performance of current encoding standards, this solution seems efficient. However, such an approach suffers from many issues ...
Separable Approximation of Ambient Occlusion
(The Eurographics Association, 2011)
Ambient occlusion (AO) provides an effective approximation to global illumination that enjoys widespread use amongst practitioners. In this paper, we present a fast easy-to-implement separable approximation to screen space ...
Compressed Multiresolution Hierarchies for High-Quality Precomputed Shadows
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
The quality of shadow mapping is traditionally limited by texture resolution. We present a novel lossless compression scheme for high-resolution shadow maps based on precomputed multiresolution hierarchies. Traditional ...
Mapping Images to Target Devices: Spatial, Temporal, Stereo, Tone, and Color
(The Eurographics Association, 2012)
Retargeting is a process through which an image or a video is adapted from the display device for which it was meant (target display) to another one (retarget display). The retarget display can have different features from ...
Perception-driven Accelerated Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Advances in computer graphics enable us to create digital images of astonishing complexity and realism. However, processing resources are still a limiting factor. Hence, many costly but desirable aspects of realism are ...
A Survey on Temporal Coherence Methods in Real-Time Rendering
(The Eurographics Association, 2011)
Nowadays, there is a strong trend towards rendering to higher-resolution displays and at high frame rates. This development aims at delivering more detail and better accuracy, but it also comes at a significant cost. ...
